If I purchase a new 05 CH from Moto parts (black one, APX) to use with my existing remote mount XTL5000 (currently has an 05 CH of the same vintage, but original 05 CH recently failed), will this new 05 head be backward compatible to a 3 year old XTL5000? Or, must I sync the new CH with the radio?

I understand that if an 05 CH has firmware that pre-dates an XTL5000 drawer, then Yes, I’d need to sync them. However, I heard (and maybe this is wrong!) that an 05 CH with current firmware is generally backwards compatible with a drawer that is a bit older, without requiring a sync. True?

Plug it in. It will either work or throw the "Maintenance Mode" display. If it works, your good to go. If you get the message, then you need to do the sync.
