    Just to add here, I've successfully ran DVI signals over 30 feet. Just make sure to buy a high quality cable. HDMI and DVI are very similar in terms of length limit and signal type.

    Thanks Tidder, that solves it.

    I checked few worklogs and found many people are using USB hub in dash with PC installed in trunk, so I guess USB would also work. But still if anyone has faced a problem with extending USB or IGN or power or any other cables in between dash and trunk, please point out.

    For valet switch, would it be possible to use steering wheel control switch, or should I install an on/off switch. Also would it make sense to have a switch between Battery and PSU (Carnetix P1900), this could be the ultimate cutoff switch.

    Thanks!

    I almost missed it. Another Camry CarPC. Yay!!!

    First up, Welcome!!

    Let’s see, where to begin:

    1. Your PC specs are great!
    2. (And #3) @SNOtwistR was spot on about the recommendations for accessories, especially the regulator, GPS dongle, and display. MP3Car is the best bet to get your main items. For all other small stuff (wiring, electrical knick-knacks and what not) a Radio Shack, a hobby store, and/or auto store are some places to check out.
    3. Okay, there is another product(s) I recommend: this OR that. If you plan to put the Lilliput display on yourself, "that" is your best bet. If you want “the easy way out,” give "this" a try.
    4. For the most part, these CarPCs are generally do-it-yourself (DIY); so that means you may have to get down and dirty in disassembling car parts to get the result you want. Not familiar with the west coast, so I can’t help you there. But I can tell you that most places will sell you the idea of using a 7” tablet in place of a PC, and overcharge you IMO so you can end up taking that route. If you end up finding a spot that will do it, that’s awesome. But if not, don’t be afraid to take a risk; you’ll enjoy the fruits of your labor.
    5. I’ve been using Garmin Mobile PC for years. I have other apps that could do the job. But GMPC is the one I currently trust. And I’m on a Mac.
    6. CarPC setup – I never heard of the car boot before (show me where that’s at!), so I cannot recommend there. You can do the armrest for the computer; that’s something I initially considered with my mac mini. The only issue is how your PC will get proper ventilation, and moreover, how will it connect to the regulator. Once you get past ventilation, you’re good. I recommend removing the armrest itself (get past the carpeting, there are two (2) bolts holding it in place), and seeing if you would drill holes through the side that goes to the shift column. If that doesn’t tickle your fancy, then I’m not sure where else to go.
    Where you put the regulator will also determine where everything else goes. One possible location is that compartment underneath your display where the DC output and aux port would normally be. If you have no plans for this area, start there. If you look at my worklog, you notice that I finally placed my mac mini in the trunk area. The reason I ended up putting the PC in the trunk was because the secondary battery that powers the PC, and the regulator, are also located in the trunk. The only long cables I have are 2 15ft USB cables, a 15ft HDMI cable (heavily shielded) connected to the display, and 2 wires from the mac to the power button that turns it on. No flaws whatsoever exist with this setup. As a matter of fact, the only problem I seem to have is with the display itself; but the remedy cannot be that far away.
    7. Ooh! Using the buttons on the steering wheel as the power button – I’m mad I didn’t think of that! If you find the right wiring, then it is very possible. Keep us posted on this!
    For what I did, I have two (2) separate buttons on the front (where the AUX Port used to be) so the regulator, and the PC, can come on at command. There are options, so do some research before you get started!
    8. You can use the harness for the power supply’s remote start. For actually powering the regulator, and therefore, the PC, go for direct connection to the battery.
    9. I return to my #2: do you want to keep the stock stereo? If not, then use #2. If so, then get the external version to the 7” display. And whatever you do…
    GET AN AMPLIFIER!!
    Do not get anything fancy or huge; but just get one that will provide better sound to your PC.
    10. Returning to #6, I reiterate that the long cables I have running to the front have given me no issues. So if you’re afraid of the PC being in the trunk for that reason, don’t be. It’s fair game for the P1900 either way, but to safe, I’d keep the PC close to it. You can always extend the power cable for the display. Messing with the PC power… I dunno.

    Not sure what you’re planning to do with a PC in your car, but I’m sure you’ll be fine. As already stated, keep a worklog, and best of luck to you!!

    Hi Pkaush, welcome to MP3car.com!

    I live in Fremont too! Good to hear there is another local MP3car.com member in the area. I would love to look over your car and help come up with a plan for install.

    There is some stuff you can have a local stereo shop do, but most you have to do yourself because the shops do not know much about carPC's. I just started 1 year ago building my first carPC, and I got a new car this summer, so am working on my second carPC.

    I built an in dash unit the first time, but went with a trunk mount this time, because there was just too much to fit in the dash, and access is hard. I have already taken mine out of the trunk 5 times to work on it, and it's real easy now. I also went with Windows 7 this time, but had Windows 8 on the last carPC. Why? Windows 8 eats up resolution, and the Metra interface is a waste of resolution, with the meat of the content in the center of the screen with pretty border colors. My screen could do the resolution, but I could not read it.

    I went from a 7" screen to an 8" screen and from Windows 8 to Windows 7. Big improvement in accessability if you ask me. If you can do HDMI, that's the best, just choose 720p resolution.

    Where to buy stuff? Online. There are no carPC supplies out here. Maybe a few connectors and cables, but mostly it's buy online.

    Mechanic to help install? I could help you with your install and advice since you live close by. Some stuff can be installed by a stereo shop. I used Capital Stereo on Fremont Blvd. to install my Speakers, Backup Battery, and Amps.

    I found out how to take everything apart in my car by joining the Camaro5.com forum, and reading the how to's for stuff like dash removal, speaker wires on which connectors, etc. You will have to find the forum for your car to find the how-to's. I also have all the plastic pry tools if you need to use them to safely get things apart, but it's surprisingly easy to take cars apart these days.

    If your battery is in the trunk, things go even faster, but if not, you might want to get an amp installed in your trunk, and have the stereo shop run 4 AWG wire back to a fused power distribution block that you can use to power the carPC, 2 powered USB hubs (one for up front and one for the back, and audio amplifier. It will make it easy to expand with more devices later on.

    I think, yesterday was a great day for my Carpc :-)!! I got great advice from Project07MACry, and found a local MP3car member, Rray, who is willing to help me - yay!!

    Thanks Project07MACry! I appreciate your time & effort and great suggestions. I went through your worklogs and I really like your display - 10.1 inch, and would definitely try to get something bigger than 7 inch (if not 10.1 ;-)). I am more inclined towards capacitive touch screen display. But I would be glad if you could give me some suggestions about where to find 10.1 touch screen display within the frame for Camry.

    The only major thing that is blocking me from doing it myself is drilling holes. Did you have to drill through the firewall to pull wires from battery to dash/trunk? Or is there an easy way out.

    Rray – Thanks for offering to help! I was really hoping that I would find a carpc enthusiast in bay area, and he will be able to point me to a mechanic. Well it turned out better - I would love to do it myself, given I can get my blueprints approved from you before getting to the implementation phase.

    I haven’t yet figured out the benefits of the second battery, so I will try to find some posts on that and try to understand it.

    I am glad, I will have help if I mess up my setup or my car.

    Thanks Again!!

    PS: I am sure I am going to have lot more questions later - so please keep an eye on this thread :-)

    I love capacitive and that 7" you linked to would be a very easy install for a novice.as it should be a remove old and refit the new..very quick...I've got a 10.1 chalkboard electronics one. is really nice but it took a while to fabricate the new dash to fit it in.I'd say totally worth it as I have a 4x4 and I use it for mapping when I'm offroad.
    With the wiring don't be scared just double check everything before you drill.a fair chunk of the wiring will he within the cabin so not to many holes to drill there...if the pc/extra battery (i believe a second battery is a must)is in the boot most wires can be run to the dash without any drilling.
    I'm sure rray will will steer you in the right direction as he does some very nice work.

    On the second battery topic....good points are engine/body electronic noise isolation from the carpc....your car will always start....the pc at the start of the install will always drain you battery at least once during the first few months!!!!.....and never have to even think about engine cranking voltage drop.

    I have learned a lot from the members here over the last year, and also learned a lot building my first carpc, which I am improving upon with the second build I'm doing right now. It's nice to have another local carpc guy around. You can always learn something from someone else who has idea's to share.

    Thanks camo.b & rray!

    I found few thread reporting issues with the alternator on connecting the second battery and jump starts, all the fun stuffs. Unfortunately, I use my car to pick and drop my daughter to school and thats something I cannot miss because my battery played dead with me :-(!!

    So I though more about it, and then some more .... and some more and then I read thread on surface pro. And I had a plan to buy Dell Venue 8 pro, so I ordered that online. Wait a minute, 8 inch windows 8.1 tablet (NOT RT), 10 hr battery life, quadcore atom processor, 2GB Ram, MicroUSB to connect a USB hub, awesome display and great touchscreen integrated bluetooth and wifi. From the reviews, it takes 1 second to come back from sleep and 5-6 seconds to boot. I can confirm it once I have received mine. Hummmm - doesn't it sound like a good candidate for in dash carpc.

    It has Windows 8.1 x86 (again not RT), and would be able to run all the stuff we use on PC and definitely will have better display and touchscreen than any other lilliput or Samsung option. All the front ends should work nicely. Also it costs just $300 which is less than the display I was planning to buy.

    It is 8 inch and should fit right in the dash of a double din frame. Has a MicroUSB port so we could connect a USB HUB. We donít need ports for wifi and Bluetooth dongles because they are inbuilt. I guess GPS would also be there, though I am not sure if that would get satellites from in dash. Headphone jack could be connected to an amp for in car audio, or we could use a USB 5.1 soundcard.

    I know using a tablet would be like less fun because there would less issues to fix, but could be a great next step to good in car display and touch screen. And if we have less issues from the past to fix, then we could concentrate better on future innovations. I have not yet decided to go this path, but it would still be a good to ponder over the pros and cons. Please feel free to list down pros and cons we could come up with. I have listed down few problem to solve:

    Problems to solve:
    1. It uses the same port for charging and connecting USB hub, so we need to find a way to solve that. There is an unofficial fix - Dell Venue 8 Pro - USB charging while a device is connected.

    2. How to switch it on and off if the power button is not accessible.


    Question:
    1. Given the power consumption on this device is very low, would we need to pull wires direct from battery, or can we just use usb adapter to car lighter port.

    2. How would you suggest to connect power to amp? can we just use the stock stereo harness?

    I Saw That One The Other day...And I Thought The Same Thing As you.i Also wish that was around when I started my build....The only possible problem with the Dell is the single use port and the switch flipping.but this just needs to be automated upon starting the car...I'd also bet that the tab wakes up when it starts to charge.....I think you would need to start with a powered usb hub and a usb otg cable...Chop the end of the otg cable....run those power wires to a 5v 2amp power supply and run the data lines to a small double pole relay....so when you crank/start the car the relay is powered up with the starter motor and shorts the data pins.(charge mode enabled)...When the car starts the car key is back on ignition and the relay loses power and goes back to connecting the data pins to the hub.and your good to go....only problem is the constant disconnecting of the hub.
