Im trying to insert code for car radio BMW Dolby BCNR. Screen has been displaying WAIT for some time. Ive discontected the battery but problem persists. Any suggestions?
Please note that code entry is only possible when the display shows "CODE - - - -". If the unit is codelocked, leave it switched on for up to two hours and a further attempt at code entry should be possible.
