absolute fantastic piece of kit alot better than i was expecting. can stream my music and calls are very clear. menus are easy to use with a voice stating what menu you are on so you don't even have to look at the screen while you are driving., the microphone is probably a bit further from my mouth than it should be but my voice can still be heard at the other end of the line clearly.
my only gripe is that the remote looks a bit tacky on the side of the seering wheel. a complete design change is needed there.
Installation was alot easier than i thought. i am by no means an electronics expert, it only took me about 30 - 45 mins to install. No need to waste 60 pounds+ on getting a "professional" to install it.
I would say though, if you are using an SOT lead, there will be a hell of alot of wires behind the stereo so this could make getting it back in fun.
