DOA, installed it in my Tacoma. Tried to power the unit on and it would not power up at all. This is the 2nd chinese, no name brand i purchased from Amazon and both times i've had bad results. I'm going with a more proven name brand.

I ordered this and it didn't have a user's manual. The GPS map card came in 2 pieces and when the unit is powered on it makes a hissing and also is automatically on high volume. The backup camera isn't very clear it's grainy
