VERY GOOD REMOTE!!!! I am extremely pleased with mine. Highly recommend. Favorite features include... digital, so no more messing with knobs & they won't get bumped & different cars by same remote and each has its own setting so you don't have to change it everytime. Negative...well,...it is FM SO....you have to have FM receivers in all your cars to use it (Like any FM Transmitter)..other than that..great!
