Want this question answered?
It's done with a code reader plugged into diagnostic port under dash.
THIS RADIO IS "THEFT PROTECTED" WHEN POWER IS LOST FOR WHATEVER REASON THE RADIO IS DISABLED UNTIL THE SECURITY CODE IS ENTERED. THERE SHOULD BE A RADIO CODE CARD (SIZE OF A CREDIT CARD) IN THE ORIGINAL OWNERS MANUAL. ENTER THE CODE AND THE RADIO SHOULD WORK....cls
You need the 5-digit code for the radio. The system locks when power has been disabled or the radio removed from the vehicle. Call a MB dealership. I have the same problem with my '99 SLK230. I know the code too. The book says if power has been interupted and the code has been entered incorrectly more than 3 times, the system will lock itself out. However, the book also says that once the radio is on again it should reset itself in 10 minutes or so. I have let my car run with the radio turned on for more than 30 minutes and it didn't reset so I could enter the code. Now, does anyone know how to fix this?
try unhooking battery cables and then rehooking them up, most of the time that will reset the computer if not you may need a new computer for it, and they are not cheap!!!!
There is nothing to reset except the radio. Insert the 5 digit radio code to reset the radio and then reset the clock and presets for stations.

To reset the radio on your 1987 BMW 3225is hold down the on/off button. Once the radio blinks twice you can choose the first radio station that you want set. Follow this on the rest of the buttons and your radio will be fully reset.
