Review on Enhanced Android Bluetooth Navigation Support: Double the Functionality by Doug Virden

I bought this for my Tahoe 09 with Bose enhanced DVD system. Also got a wiring harness from Crutchfield to make installation as easy as possible. Everything worked fine and the screen looks good. However, the head unit wasn't compatible with my amplification system, so the volume was low and my subwoofer wasn't loud enough either. I contacted the seller via email and they tried very hard to resolve the issue but unfortunately they were unable to resolve the issue for me. So they refunded my money without hesitation and even told me not to worry about returning the product. Excellent customer service!
