I wanted an "all in one" unit with gps & navigation for free.
I've got this one (from 2015): http://www.autopumpkin.com/car-dvd-...remote-control-for-opel-vauxhall-vehicle.html
Best thing: Some guys from XDA like to develop new fw: http://forum.xda-developers.com/showpost.php?p=58249825&postcount=7614
Negative: Radio sound could be much better
Positive: Absolutely stable, even when I navigate for several hours & fast gps fix. Sound is very poweful ( when you listen from sdcard or BT (even with the crap Vauxhall speakers)
