i bought a Z2 about a year ago and a friend installed it for me, it worked fine for a good while but a couple of months ago it started freezing on me when i turn the car on.
sometimes the start up screen will go on and then go blank, or sometimes the start up screen wont even go on and just stay blank from the start but still play music only untill i press the reset button and then just goes off all toghether.
If anybody had similar issues or an idea of why this is happening please share.
