4 string with out upsetting you ...radio was made for a market where its mostly European cars with no dash space for large radios hence DIN sized
most of the other things you didn't like were stuff you could of noticed in online write ups and pics before buying
didn't know free banders talked in channels...over 30 years as one i have issue even remembering what channel is 27.385! ..from my understanding its a American thing to speak channels out side of the legal band ...easy to spot a day to day cber if they call 27.555 channel 12 band something lol
