This seems like a pretty good radio, reception and sound quality, by RV standards but we haven't used it too much so no idea about durability.

I have a 2005 Coach House RV that originally came with a similar product with a VCR in it. When that original one went bad about 3 years ago, I did not find this or a similar product that fit the shelf it set on. So, I got a more upright style and installed it behind the TV. Not ideal but I made it work. When the surface on the new one turned into a black sticky mess, that got on my hands whenever I touched it, I ripped it out and went on a hunt for something else.
I found this. It fit the hole perfectly from a size perspective. However, the original one was a shelf system and this one requires mounting, so I made some mounting brackets. The wire color on this follows industry standards, so removing the old connectors and installing the connectors for this was not a problem. The only caution is for power you MUST connect both the power and AUX power for it to work (it is 12 volt power only). It has good sound, the radio, DVD player etc all work well.
The only issue I have is with the Android app. The symbol that should take my phone directly to the app did not do anything. When I tried to find the app as listed on the phone I did not find it. I found a couple of others that I thought might work, but so far no luck. This is not an issue for me as I likely would never use it. But, something others may want to be aware of if that is an important feature. Just finding a receiver/player for an RV that fit nicely in the original space is a big win for me.

This replaced a coby surround sound player. Wanted this one for the size, had limited shelve space, but more importantly have the 5.1 surround sound so I could use my exciting speakers. Made my own face plate to match the wood in the trailer. Works great and sounds great too.

Ease of installation, great sound and great price

I purchased my first one but didn't wire it correctly so I ordered a second one and sent it back. Once I wired it correctly. It's the best thing ever my travel trailer hasn't had surroundsound in about 10 years. It was really nice to get all that back.
