1995-2005 GMC Chevy Chevrolet Truck Van AM FM Radio with Bluetooth Music

I have an older GMC pickup truck and wanted to keep everything the same as original but with the bluetooth for the radio instead of the existing cassette player. When I placed the order I don't think I was asked if the existing system had a separate CD player. When the radio came and I installed it that CD player didn't work. I called the vendor and they told me that the radio I had did not work with the CD player and they sent me a return slip which I used to return the first radio and then they sent me the correct one. This transaction worked smoothly but could have been avoided if the correct radio was ordered in the first place. When I installed the second radio I was experiencing sound quality issues but after a call to the vendor I was directed to work thru the volume adjustments on my iPhone and the radio and that worked. Now I am very happy with the changeout and found the company excellent to work with.
