true!!!
I for sure plan on shaving mine on the next car. I am going to wire it into the keyless entry panel though so instead of locks, It will pop the door. No hidden button - use the special code instead. This way If I forget my key fob, i can at least still get in the car.
As for interferance in the radio - if it is aftermarket radio i would say DEFFINTELY hear the fuzz. I can't seem to get rid of the HISS in my new system.
