This review would have been better if a) the instructions were a lot more clear b) the package would have come with a wireless transmitter and receiver rather than two transmitters. Overall, the radio is a nice unit. I replaced a factory unit test only had CD and tape so having the ability to play from a mobile device, USB drive, SD card or CD is a giant leap forward. I thought this unit was supposed to play DVDs directly from the unit but have yet to get that to work (plus when I tried, for some reason the CD I put in next wouldn’t play either. This corrected itself after turning off, and back on, the car). I drive a fairly large SUV and the unit is mounted almost dead center and the couple test calls I made were crystal clear, which surprised me because it looks like the microphone is on the opposite side of the unit from the driver’s seat. The remote will take a lot of getting used to because there are so many buttons but it seems quicker to access certain menus when listening to music. I do wish that I could use the remote to dial a number without having go to the Bluetooth screen and press the icon. Seems like I should be able to do that since there is a number pad on the remote. The internal preamp is heads and tails over what I had before. That is bad because now I realize that my speakers will need to be replaced, those factory speakers can’t handle the power when you get close to 50% volume. But it is good because the aftermarket speakers will not, in general, require an amp also.
Earlier, I mentioned the instructions. They are completely useless, so go ahead throw them out right away. There is, literally, a half page (including a drawing) for installation instructions. This was my first backup camera install and the instructions didn’t even mention this with the exception of labeling the trigger wire. Oh yeah, and they don’t mention that it is a trigger wire, they say it is a +12VDC ACC wire. I fumbled with that for quite a while before I googled it and learned that is just a trigger wire. Then after getting that all finished the camera didn’t work because both sides are trying to transmit. I could have used the 20 foot RCA line had I not put my back window down and chopped off the 12 volt RCA connector to the camera.
Hope this helps!
