When memory is lost, most radios needs a reset code so that must be the reason the radio does not work.
The system mentioned was started in the late nineties by Merc and has since been scrapped at our end. After battery removal, the PCM has to be reset in order to start vehicle and that means getting the vehicle towed to the dealership if the battery were to be removed.
Hope I am talking about the same thing.
I agree about the cigar lighter plug in but as mentioned, take care not to short the battery terminals. Don't forget to ensure the cigar lighter plug is functional before attepmpting it, you might be in for a surprise.
