This is the one i bought:
its dual core - way more then enough to put in the car.
rooting the stick took me a while to find the right method for this specific model, but i got it and it worked like a charm. rooted in 1 minute. If u guys end up buying the same stick i will upload and write instructions.
i have the App Radio 3 with the pioneer original android cable kit which is perfect.
it give power to the stick and it is connected via HDMI.
there are other custom ROMS for this stick but i found them useless to my needs since all they do is claim that 1080P support is better improved, which is irrelevant to our case since we never gona stream 1080P in the car.
i set up my google account and it took me roughly 1 hour to get everything set up the way my phone is...
since its an android stick and im not afraid of battery drain i put a live wallpaper on it
which was cool.
it get internet via my phone tethering, works like a charm.
the first initial set up needed a keyboard and a mice. after that i also purchased one as a backup:
just to have it in the car, just in case...
also dont forget to buy this if u are using an HDMI cable coming out of ur App Radio:
other then that ARU-Reloaded worked perfectly on that model,
sometimes the stick BT get disconnected , u know like any other software they all got bugs, but after 10 seconds its reconnect and ARU - Reloaded recognize that and reconnect automatically.
ARUR is set to start on boot so all i need is to turn the car on and i measured 1.30 minutes till i get touches.
GPS always worked for me with zero issues when ARUR is connected.
