Becker Grand Prix Model BE 754
Used in the 1986 and 1987 Mercedes.

Single-piece unit electronic AM, AM Stereo, and FM radio with automatic seek tuning and cassette player (with CrO2 tape switch and Dolby B Noise Reduction), and with anti-theft. Cassette must be manually inserted and ejected.

One of the best AM Sections of any radio ever produced. Had over twice the audio power than the 81-85 version Model 612 which only had 7 watts per channel.

Uses a back-up battery. The radio (used in '86, '87 and some '88 124/126s) was supposed to have a mercury battery that would maintain memory as long as the alarm wasn't set, but the batteries they used went dead within 6 months or a year (rather than the 5+ years predicted).

You can send the radio back to Becker and they will replace the battery for a about $75.

This unit does not have a numerical code. It has a theft deterrent system hooked into the car alarm system.

Came with anti theft circuitry that needed to be reprogrammed at a MB Dealer or Becker when triggered. The model 754 radio was not designed to deactivate when the battery was disconnected. If the 754 is doing that, it simply means that the radio's internal lithium (or mercury?) battery is dead and it needs to be replaced. Once replaced, you can disconnect the vehicle battery and it will not 'dash-out' on you.

If you have 4 dashes across the display the unit needs to be sent to Becker for repair.

If the backup battery is dead, disconnecting the car battery will blank the display and it must be reactivated using the dealer tool with the radio installed in the car. Some dealers (American Service Center in Arlington, VA) will reactivate the radio gratis, some dealers will do it if you slip the service writer a $5-10 bill. Some dealers charge $30 or so to reactivate the radio.

Can be modified by Becker with an auxiliary input to accept an MP3 or iPod.
