If that's a Dynavin unit, I wish you the best of luck. I sent mine back for the following reasons:
- Volume clipped way before the OEM unit
- Rear speakers didn't work (since discovered that you need to plug an adaptor directly into the OEM amp, so you will need to find this)
- FM Radio reception was terrible (comes with new antenna)
- Menu screen was slow & clunky
- Contrast on the screen was quite poor, especially for top-down driving
- As soon as it was fitted the release springs/clips snapped off, so getting it out required removing half of the dashboard, and half the skin from my knuckles...
It seems like a great solution, however in reality it really didn't live up to the hype for me. Luckily I bought it from the UK distributor (not eBay) and got a full refund for the reasons above. On the plus side the guys there were very helpful over the phone, the problems however were not something which could be corrected over the phone.
