Pioneer/Focal installed in a base model

wellarmed

Haven't noticed any with mine but then I just change one channel at a time and haven't tried machine gunning thru a bunch at high speed. One up or down flip of the switch seems to do exactly what it's sposed to. The volume control works the same as it did with the stock radio.
The installer did say that it didn't work properly following the install instructions that came with the controler but didn't specify what didn't work. Maybe there was a delay and that was what he was talking about. They got around what ever the problem was with some trial and error with the wiring so having somebody that knows what they're doing is a good thing.
