I’m looking to swap the lr3 radio with another of the same from a RR sport.

Do I need to reprogram or is it plug and play?

(the head unit has no sound - very intermittent, and the right **** will not adjust any of the balance/fade/bass/treble functions)

 

You can just swap em, no programing needed. Also it could be the AMP, the radio on these are for the most part a dummer controller, the amp does the heavy lifting.

 

thanks. I thought as much.

can I use an amp from a 2009 rr sport with the same HK set up with the MOST connector? Am assuming the amps were pretty much the same for the run.

 

Best to match amps, there are a couple variations. Logic 7 or not, etc.

 

Ok. Does it need a re program. Or much like the head unit. No issues?

 

Nope, just swap and you are good.
