Navit is an open source turn by turn directions app using the free Open Street Maps.
It is important to note that both the app and the routing engine, along with the map data are all Open Source!
The app is in beta still and can be downloaded using Cydia. Add this source http://szndvc.dyndns.org/cydia/ and then search for "navit"
You need a planet.bin file of the Open street maps data. You can use this http://maps.navit-project.org/planet.bin but they have a tool that lets you select a portion of the map to download. http://maps.navit-project.org/download/ That file will go on your iPhone at var/mobile/Media/Maps/planet.bin
There has been a lot of discussion about community generated maps. Cloudmade and openstreetmap have made immense progress, but their big drawback is that it required active user input to have the data be routable or reliable. Teleatlas has jumpstarted community generated maps by releasing a paid passively generated database that has been created and augmented by free passive user inputs. (teleatlas press release )
In this Youtube interview Rik Temmink boasts 7 million reports in 18 months which have generated 1 trillion gps measurements on the road network. He describes the beauty of passive user inputs.
The big drawback here is that Teletlas is now charging for these maps generated by their users. Why can't we hack our PDAs, phones, and other devices to create free maps? Most people don't think about the super high costs of map data. Hopefully the community can unite:
Collecting and sharing GPS data
Writing an algorithm to process this data into routable and usable information
Cleaning up open source algorithms to use this new data
Back in march VIA announced the new automotive ivp-7500 (press release ). The announcement got some press from slashgear , crunchgear and has spurred discussions on our forums .Via claims onboard support for Bluetooth and GPS, which in all reality appear to just be add on modules.It seems like VIA took an off the shelf board, slapped on a few modules and rebranded old tech to create the appearance of an automotive solution. This might be perfect for a hobbyist or an R&D lab but you can forget about auto provider shipping silicone with a 0c-60c spec.If someone from VIA would like to explain the press release in more details, please post on the forums or e-mail us. We would be happy to write some revised commentary if there is something we are missing. Talk about this Blog post on our forums.
Some intelligent forward thinking researchers over at Hitachi, Xanavi, and Nissan have collected some data on ecological green routing that claims a 9% fuel cost savings on a test route. This technology is still in its infancy, but this is a perfect example of where a car computer can be used to accelerate development and deployment of technology. Implementing ecorouting will require Intense processing on the client or cloud for the complicated routing algorithms that factor in all the newly available data points:
· Traffic & Flow speeds · Elevation changes and altitude · Road quality (smooth vs. rough) · Wind (eventually)
The cloud or development computer can also be used to coach the driver into more efficient acceleration and braking techniques which a lot of hyper milers are already using. Eventually I imagine this type of data would help local governments prioritize road resurfacings and traffic control timings to help their citizenry become greener.
It seems like one of the key pieces to making this work would be accurate elevation Data. The paper I mentioned above used 50m resolution data from the government. One of the key data providers for elevation data seems to be intermap with 5m horizontal resolution and +/1 1m vertical. Check out their comparison chart to NASA data.

Goce from mp3Car will walk you through the steps necessary to power your laptop using unregulated ~6~24 volts with only the p2140 and the wire your laptop power adapter came with.
-For this project you need the following materials: -p2140 and 8pin molex output harness -Wire strippers 14-22 gauge -Bench battery -Multimeter -Shrink tubing and heat shrink tubing gun OR electrical tape -Solder gun and non leaded solder -laptop and its power brick -knife or scissors
To finalize this project you should do a continuity test on the stripped wire to find out which is positive and which is negative. Then you can twist and solder the p2140 output wires to the cut laptop brick wires. Turn it on to test it one more time, and then plug it into your laptop to test.

The basic procedure here is to cut and strip the laptop power brick, while NOT cutting the multi-strand wires right beneath the black plastic. Then soldering the positive wire of the primary output from the p2140 to positive end of the now cut power brick cord. And then the same for the negative.
In the next video we will show you how to test the polarity using continuity and then actually test turing on the laptop using only the power from the p2140 (through the bench battery of course)
mp3car's Robert Wray interviews GENIVI's board member Joel Hoffman in a 2 part interview. Part 1 of 2 covers: What is GENIVI, How did it start? What are the first topics GENIVI will address? What is the Link between GENIVI, Linux and Moblin? What are the costs?
Part 2 of 2 covers: What actually is the GENIVI scope? What areas do you expect to cause conflict and how will association conflict be handled? Why are parts of development closed?
Robert Wray from Mp3car is in Detroit at the “telematics update” show. Our forum users are almost always about 3-5 years ahead of most automotive labs and public displays. This development gap makes these events sometimes feel like big industry group hugs, but every now and then there are a few gems. Want to hear about something specific?

Hi my name is Robert Wray from Mp3car. Throughout the summer we are going to dive deeper into the future of mobile computing, car computing and telematics with a series of video blogs exploring new technology and interviews with leaders in the space.
Based on our activity in the community, our work with automakers, aftermarket, communications and telematics companies, we believe consumers will demand a bunch of new features all seamlessly integrated into a replicable, flexible UI and accessible from many devices of varying power, age, screen size, and interfaces.
The feature list will include. • Connected navigation (Internet POI, Real time traffic, regular map updates) • Media & entertainment from the internet or internet connected devices • Interfacing with other technology (engines or batteries, GPS and other location indicators, other sensor hardware) • Extensible developer interfaces to allow rapid add ons and integrations with existing features • Demand for skinable and user customizable interfaces • Occasionally connected devices (wireless, USB, WIFI, sneaker net) • Demand for flexible audio and visual prioritization • Flexible Security & Personal privacy awareness & settings • Task aware user interface, for example - user taking a bus, driving, walking, sitting down • All of the above components, including the UI should be modular and replaceable at any time to make way for new innovations.
Through our video blogging and interviews we plan to find out what it is going to take to make these features a reality and follow the activity of our community members as these bleeding edge features get implemented.
Some forum members were already talking about this mobo but I thought I would shine some light on the subject. I had a chance to play a little bit with it and see if it's working etc.
Form factor Mini-ITX /micro-ATX compatible
Processor Integrated Intel® Atom™ processor 330 with a 533 MHz system bus
* One 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM) sockets * Support for DDR2 533/667 MHz DIMMs * Support for up to 2 GBΣ of system memory
* Eight USB 2.0 ports * Two Serial SATA ports (3.0 GB/s) * One parallel ATA IDE interface with UDMA 33, ATA-66/100 support * One serial port * One parallel port * PS/2* keyboard and mouse ports
I tested this board with the following config: - 80 gig seagate SATA hdd - 300 w power supply - 2g of DDR2 800MHz Buffalo ram (1 stick) - Dell mouse and keyboard (both usb) - memorex external DVD via usb
The board was able to install XP Home flawlessly, and so far, is very quick. Startup time 46.8 seconds and shutdown time was 8.5 seconds.
You can't look at this board without comparing it to the previous LF2 model. Unfortunately the only thing I was able to find, along with others here on the forum, the S-Video is the only difference. The previous model has it and is priced on newegg for 79.99 and this model doesn't have priced at 76.99 on newegg.
So it seems for $3 less you can get a board without S-Video. Why not include DVI or display port on the next model?

Ride Runner
The community is helping DocBreezy bring a sleek new skin, named '506' to Ride Runner . by DocBreezy. Picture: http://www.mp3car.com/vbulletin/imagehosting/14883749a87d9096277.png In addition to suggestions and beta testing, Treetop, Thunderstick, blk02si, Sonicxtacy02, GizmoQ, carputer1are lending a hand with advice and code support to bring it along.
506 also builds on the flexible plug-in architecture of Ride Runner by using: - RRGas -Enforcer's gas price finder for US and UK - Movietimes - a plug-in that retrieves movie times for your zip code (US only) - Coverjuke - an implementation of Coverflow for Ride Runner.
- MyMobiler is a Windows mobile phone control program that can be controlled from the skin.
Community Development
Just in case you don't hang out on mp3car.com forums 24X7, you may not be aware that there is a flourishing open source car PC environment for Linux called nGhost.
Version 2.0.0 is details are available here and kev000 is one of the lead developers for a team of like minded community members including:
among others. You can find the nGhost download here
Shift by wire: Automated P-R-N-D-L - Member turbocad6 is at it again with a plan to replace his automatic shifter. The community has been tossing around ideas about how to do this and ways to implement it. Right now, it looks like an Arduino board and a linear actuator will do the job for push button shifting. Got something to contribute? turbocad6 will need help programming and engineering. Check it out .
Towards a more flexible front-end. The front end is the software that ties together all of the functions that the computer offers into an easy to navigate and control 'face' for using the computer while driving. There are numerous front ends (Ride Runner, Centrafuse, nGhost, Streetdeck as examples). This thread is a brainstorming discussion about how to create a more flexible front end that requires less configuration and tinkering yet runs across platforms. If you've got ideas or want to see the community at work on an idea, stop by and check it out!
Lovely when a plan comes together. Check out member malcom2073's new front end, CarPal. The community is helping him to lay out a plug-in scheme for the front end, and Sonicxtacy02 is working on a skin for the new front end. A great example of the community helping to develop a software product .
Skype for RR
Member lambosprit is at it again. As if solving the bluetooth problem wasn't enough, lambosprit has a basic plug-in for Ride Runner that brings Skype functionality to the car PC. It makes and receives calls between both Skype users and external phone numbers. Check it out .
Covermess
Member pcpete has developed a plug-in for Ride Runner called Covermess. It's a Flash app that displays your albums in a pile, as if they were real CD's. You can select and play music from them, similar to the Coverflow display on an iPod. Check out the video in the first post for what it looks like. A really nice bit of programming !
The Unexpected
From spud cannons to automated pyrotechnics controllers the community continues to innovate and develop new and very unexpected uses for hardware. Find out how a plastic toolbox and a Fusion Brain = pyrotechnics controller.
The Fusion Brain is one of the most popular hardware add-ons for community members. Developed by two of the community members, 2k1Toaster and greenman, the FB allows your computer to interface with the outside world in both analog and digital fashion. Using standalone software, the FB can be programmed to read temperatures, control relays, stepper motors, infrared sensors and so forth. Car PC'ers use them to operate windows, switch relays on and off, read temperatures and even control Christmas lights on their car
Lilliput is getting ready to release their new 7" touchscreen that has native DVI and component digital out. Previous models such as the 629 had only VGA, Composite and S-Video.
What is great about this monitor is that it's now extra versatile. They left the pigtail plug on the monitor and just added the extra DVI and component cables. That means you have the option to output to 5 different video sources, DVI, VGA, composite, component and s-video.
The connectors for DVI came out of the bottom of the unit, whereas the pigtail connector came out of the side. So this may affect some installations but just be aware that it *may* be changed.
The digital output was, in our opinion, more defined in terms of the colors. More specifically the blacks were blacker and the whites were whiter.
The only down side we noticed is that the DVI output seemed to have off colors. The ocean in the video seemed very green, even though on VGA it was blue.
All the settings for the test were brightness 50% Green 50% blue 50% and red 50% with a resolution of 800x600. They ran from the same ATI graphics card playing BBC's blue ocean on VLC player.
This product should be coming soon to the mp3Car store, so look out for it.
If you have any thoughts on the monitor talk about it on the forums
You don't need an expensive hybrid vehicle or car computer to get the most miles per gallon out of your car. Hypermiling is a set of techniques that maximize your MPG.
Some common techniques are: Don't drive aggressively Don't go over the speed limit Avoid traffic Avoid coming to a complete stop Try to accelerate as slowly as possible Using neutral when going down hills
Some uncommon techniques are" Drafting behind trucks Using centripetal force to go around turns fast Over-inflating your tires to reduce friction
We took a look at how what kind of MPG we got out of our Toyota Matrix when doing basic hypermiling around town. We averaged 61 MPG when hypermiling and 27 MPG when driving normal. At some points on the trip going down hill in neutral we got up to 247 MPG.
There has been a lot of discussion about community generated maps.
