becker cdr 220 radio code

[EssexPorsche]

don't think so.
I have had the battery off mine more times than i care to count... and for long periods.

Every time i put it back on - radio does not need a code and my pre-set stations are still there.

I read that the radio knows which chassis number it belongs to, so when you power it back up after a battery change, it calls the DME and confirms its in the right car. So long as the VIN matches its all good. If not....it locks it out
