Radio reception sucks now

Any idea what would cause my radio reception range to degrade? all of a sudden my radio reception sucks... Bad antenna? Fuse? multiple antennas?

First guess would be bad antenna. Dealer diagnostics should pinpoint exactly.

radio fix

Bought a ICARSOFT hand held scanner and ran it to check and reset codes on my GL450 and now some how the radio reception is back to normal...
No idea how that can be but it is.

You cannot perform radio diagnostic with a generic scanner. You need DAS for this (and pretty much everything else) to make sense of the codes / read all of them and troubleshoot effectively.

On the antenna issue- have you checked if the episodes o bad reception correspond with using the rear defrost?
