i have tested something similar, and my results were that it just wasn't reliable/speedy enough which is why i went back to just using it to trigger on power. the other route you may want to think about is getting something like the blackberry music gateway that has auto reconnect built in. it would mean more $$$, but sometimes it's worth it to spend the dough in order to minimize headaches.Quote:

However if the 'always on' setup is not fast enough (perhaps it will be with blackberry/tunelink), I have to consider maintain the actual 'switched' setup. I have to try if I have no noise with belink.. because, in case of noise I am forced to try the Tunelink.. :-\
finally found the plug needed for powering belkin bt via usb cable!

unfortunately, even the belkin has a lot of noises, similar to the other bt receiver I tried.
Ok, I knew I should start with the best: I'm converting to that TuneLink thing..
Hi guys!
Sorry for the loooong delay but I was very busy trying different solutions for my install. The longest delay was caused by the.. communist party election in china, because all deliveries was delayed of abouth a month! All cables and adapter I ordered at the end of october was only delivered few days ago.
I have tried so many different solutions for removing the audio noise (alternator whine) tha you could never imagine: now I'm at work and don't have my photo collection here, but this evening I'll post some to show you all my tries :)
However, at last I find the solution: the one and only way to completely eliminate audio noises is bluetooth audio transfer to the TuneLink Auto adapter. This has the best circuitry, made specifically for car use.
I'm also experimenting different software and application, will do a list soon.
Thanks to all the contributors to this great forum, I constantly grab ideas from works of other posters ;)
This is a great thread.
I like the work you have done and I think I will move from using my current setup of a Sony Vaio laptop and Xenarc 8" touchscreen to an Android tab. Just a much cleaner look. Thanks for your informative posts.
Here are proof of my many attempts:
- another user gave me a great idea: trying to get audio from the dock hdmi out port! I bought the cable form ebay (can't remember the price, about 5 euro I think)
Attachment 68583
Once arrived I realize that the dock has MINI hdmi port... damn, ordered an adapter (2 euro) but had to wait another month..
Attachment 68584
but nothing changes, so much noises..
Searching for that hdmi cable, I found another interesting adapter: a galaxy tab <-> rca cables + usb power. Perhaps avoiding the dock audio out circuitry I could avoid all the noises!
Ordered, (about 3 euro), wait TWO months..
Attachment 68585
..but no, even with this, I got noises.
So I made my decision and bought the TuneLink Auto for Android. I was lucky enough to find only one unit on amazon italy for 72 euro (yes, it'a about the regular US price of 99 usd, but all online stores here in italy sells for about 100 euros..)
Attachment 68586
Let me tell you: this device is AMAZING! no noises at all! They said it is made specifically for car use and it's absolutely true. The tab connects to it in a couple of seconds and Poweramp resume playing (more on this later)
It also has an usb port to charge your device, providing about 2A. The only problem is that Galaxy Tabs wants its specific charger, otherwise it would not activate the fast charge and gets only 500mA from the charger.
Tunelink Auto has an android app to setup all parameters (it has an Autoconnect feature and can also stream the audio via FM) and it has a setting for charging: android or non-android device. I Tried both but the tab won't charge.
I contected Tunelink customer service and they ask me to do some tries with no luck. So, searching on the web (it's true, google is your _best_ friend) I found that the only difference in galaxy tab charger is that the data pins are shorted together!
So I bought a simple adapter cable, it has a switch to select 'data' or 'charge' (2 dollars on dx.com)
Attachment 68587
and insert it between the Tunelink and the samsung cable
Attachment 68588
Finally it works! The tab is now charging :)
After all these tries, and being able to eliminate all the noises, I decide to remove the two filters I left on power calbes. As I said earlier, it barely remove some static noise, and without that, I have no noises too.
Attachment 68589
and now I have a much cleaner install.
(continue...)
The next issue I have to solve (don't you believe there is no more issue uh?) is that charging the tab via Tunelink isn't enough to counterbalance the discharge during the standby period. On workdays I use the car about 20 minutes in the morning and 20 minutes in the afternoon, and the battery discharges at about 2% every hour of standby. It don't seem much, but every day it has about 23 hours of standby..
The Tunelink is able to charge about 5% every hour, so in my daily use it can charge the tab about 4-5% meanwhile it discharges about 45% every day. I remember that the original charger, even if rated at 2A (Tunelink stated a 2.1A power), seems to charge faster. So I did another try (and opened again the dash..) and it's true: with the original samsung charger the tab was able to regain about 18% every hour. It can't beat the discharge rate, but it better that the Tunelink.
I bought on ebay (I'm a very good customer!) a multiple cigarette lighter socket for about 3 euro
Attachment 68593
it also has an usb port, useful for other accessories.
I removed the cigarette lighter socket mounted before and hardwired this multiple socket, then insert into it the Tunelink, the samsung car charger and the power for a dashcam I bought in the meantime (more on this later)!
Attachment 68594
Then I use zip ties to avoid that chargers come off of the socket
Attachment 68595
Now, I can finally say that STEP 2 is over (for now...) and STEP 5 (ON-THE-ROAD FUNCTIONALITY TESTING / LONG TRIP TESTING) is already started (I test the system in my daily use)
Surfing the web I occasionally saw that crazy car crash compilation, mainly from russia and nations from the east. In these countries dashcams are of common use for insurance reason and because streets seems very risky!
Here in Italy I've never seen car accidents like that in these videos, but I thought it was a nice implementations of my new setup.
Linking that cam to the tab would be great, but the galaxy tab already seems at its maximum, so it's better to use something indipendent.
I bought from dealextreme that small dash camera (about 120 usd)
Attachment 68596
it can record videos in fullhd, has auto power on/start recording and auto power off/stop recording with car's power, g-sensor (it can protect some files from overwriting when record strong shock) and gps. There are some great desktop software to review your recordings, geolocalizing you on google maps, showing logs of sensors and speed.

I was able to hide the power cable behind the rooftop and the side covers, and connect the power adapter to the multiple socket

This should go in STEP 6: FUTURE IMPLEMENTATIONS :)
And today I finally hooked the dashcam in place!

Could you provide a link or make/model for this adaptor?
