Pine64 Head Unit

[ipsw]

Hello, I'm happy to see this thread, because the original reason I bought the pine64 was to make a android-based CarPC

Here are my plan
*WiFi througt Huawei E5331 3G/Wifi modem
*GPS (Anyone have a VERIFIED GPS receiver that works with Pine64?), to use iCoyote (Waze-like). But the app itself doesn't start.. Too see later. And navigation with Tomtom app
*Pine64 on permanent 12V
*7" screen (who is already installed in the car, waiting for his Pine), on accessory 12V
*Touchscreen? Do you know if these eBay touchscreen module works with Pine?
*Music to my actual car radio (via jack or BT I don't care), to play Spotify.


My screen looks like this! It's an unique thing, as this car isn't made to accept screens, so handmade and looks dope !



I would be glad to help you on this project !
I'm currently waiting for my WiFi Module (Didn't bought it when I bought the Pine so...) and looking for a working GPS module

Has anyone tried this raspberry pi based head unit? http://i-carus.com/ It may have some useful design decisions. I have read through this thread up to here and like this idea. How can I help speed up the work on this?

I've tried, and I haven't seen any solution that wasn't crap, with RPi..
So my RPi return to local-server, and not in the car :p

By the way, sorry for my bad english 
Have a good day !
