Thanks for the update. For a different type of radio, features etc. look at
http://https://www.crutchfield.com/S...r-Stereos.html. They will instructions, technical support and depending on the value of your purchase, include installation kits etc.
For your information, the RV industry typically buy the radio with the MOST features on the time, for the lowest price. This includes MHs trailers. the 06 vintage were a lot of Magnadyne radios with the weather networks, then Clarion and others, but none of the bigger recognized names, Pioneer, Sony,etc that would cost a few dollars more.
When I replaced the Magnadyne in our 06, I got a Pioneer, more features, they also included a mounting kit from 2 din to 1 din. and plug and play wiring kits, all for $149.
When you take your MH to the dealer, you should not have to leave it. The service department should confirm that the radio needs replacing under the Thor warranty. Have the dealer call when the radio is in, go at a mutually agreeable time. Technician should come out to the driveway, pop the radio out, put new one beside it, change plugs and jacks and push radio back in , 10 minutes.
