Someone was nice enough to pass this info to me since we had problems with our IRV66 from day 1. Ours would occasionally cut out some of the speakers, channels, etc. It also would be very sporadic with the bluetooth connections, pairing etc.
I spoke with Todd and Nelson from Patrick Industries and they explained to me that the initial units had software issues that they have since updated. If you contact them within the warranty period they will ship you a new unit. You do have to send the old one back so they will hold a credit card number until they receive it.
If you aren't comfortable replacing it yourself, you can have it swapped through warranty at your RV dealer, but I'd probably expect a bit of delay doing through a dealer.
