Why don't you go back to Becker Radio. They will go over your unit for $129. To update a bit they'll had a input for a MP3 player you can put in the glove box for another $100. That's what I did with my 300Dt. Plays thru the radio speakers and sounds great. Plus, you can shut off the antenna so that's not going up and down all the time. Google Becker Radio in North Jersey.
