I asked over on the Rushmore board as well. The AVC doesn't seem to do anything no matter where I have it set.

I have the most recent software update, just want be be sure I'm not doing something wrong, or if I need to try to get it fixed under warranty. (My warranty experiences so far have not been pleasant) so if I can fix it myself, I would prefer to go that route.

 

You're not doing anything wrong, I've got a 4.3 and latest update and mine hasn't worked in ages. HD is doing something though by not firing/replacing the idiots responsible for all the radio software problems.

 

My AVG kinda worked with the stock audio Boom 4.3. Then I had the Boom I and amp put in and they flashed it with 1.19.1 (most current version) and it sounded like crap and the AVG didn't work at all. After I took it back, they fixed it (re-flashed it) and now my AVG is working well. Maybe because of the amp and speaker upgrade and I can notice the AVG better? Don't know but it's working like it's suppose to now. Maybe take it back to the dealer and ask them to look at it?
