Question Radio code - not needed newer cars?

I have a 2005 SL AMG and MB USA has no radio code in their system. I was going to disconnect the battery to add a trickle charger device and thought I might need the code to reactivate the radio.

I was advised by one dealer that a code is not necessary with the "newer" radios, i.e. my 2005.

Another dealer said I would need the serial number/code off the back of the radio which would require that I take the radio/nav out.

Please advise if any info on this. Much appreciated. Thanks.....

I was told the same thing somewhere on this forum but I don't remember the specifics. Try a search on the Audio & Telematics forum, I think that's where I saw it.
