Please, could someone give me a better answer than a kid at the dealership? I bought this 88 420sel about 7 weeks ago with a new battery and started driving it back from NJ. used dealer to Maine and turned on stereo and it was flashing "wait", so I waited, about 40 minutes and then it came up "code", so I entered the code that the dealer gave me and it flashed back to "wait" so again waited for the "code" prompt and entered it again same thing happened only this time it wasn't flashing wait, it was on solid, and has been for the past 4 weeks everytime I turn the radio on. I tried leaving it on for an hour and nothing changed. The dealer said there was nothing they could do, this sounded like, "I don't know what to do", I asked, so I'm supposed to throw away this radio and start over , and they said , well we could get you a reman. radio. I can't believe I have to replace this radio for this reason, someone must know how to get back to be able to reset the code. Dealer ran vin. # and did not have a radio code come up. I know someone has the answer out there...Please Help! Thanks, EM
