In your 2017 you should have the IRV34. Hold down button 3 and then you can adjust exterior volume as others have said. After a few seconds it will default back to controlling zones 1 and 2. You can also have a different source on zone 3 such as FM while you have something else playing inside such as a CD.
Believe it or not they sell these pieces of junk for $399 at Crutchfield
. But it was also the same when they sold Jensens. I guess since its made to be RV specific that justifies over pricing.
It will sound a lot better if you verify all the speaker wiring is done correctly. More often than not they'll have it wired wrong. They do some idiotic things like have one speaker on zone 1 left channel and another on zone 2 left channel............ They typically pay no attention to polarity either. When I say it will sound better take that with a grain of salt. You would be hard pressed to find speakers that are cheaper and lower quality than what they use. You would have to work at it.
