Hi I just changed my battery and don`t know how to reset the radio, its not in the Bentley Manual. The battery that was in the car was too small (bought it used) guess what the power windows work MUCH better now. I had disconected the passenger front window because it would run its self up and down while driving. As the battery died I noteced the other windows did the same , could be low voltage problem. I will find out . Thanks for info on radio.
