Hello,
I want to know that what affects the XPR6550 in GPS capbility?
As I got one UHF and VHF, the VHF one have CP 4.0 but the UHF have CP 2.0, will it affect the GPS as I push #123# but long time cannot get the GPS information, however, the VHF got it shortly.

Thank you!

Upgrade both radios to the newest firmware, they may not have all the patches correct on firmware that old.
