I replaced the original Jensen that came in 2016 R-Pod RV. The CD/DVD player no longer worked. I did an Google search for the replacement. Walmart was $140 less than Best Buy and Amazon! Took a week for delivery. Installation was easy once I identified all the wires (there is bunch of wires!). Luckily all the wires from the original unit still had the ID tags on them and the new unit was tagged the same, and, the new wires were all the color coded the same as the old unit. The new unit size was exactly the same as the old unit. The new unit requires one to download the Jensen APP to get the blue tooth to link to my Iphone. Took me 3.5 hours to install as I said previously there are a lot of wires. My RV only has 4 speakers, this unit has capability to add 4 more speakers(8 extra wires). I was very careful to do one wire at a time. I Tied off the unused wires and snip their bare ends. I then mounted the new Jensen. Probably the hardest part was getting the old wires nuts off as they were crimped very tight. I replaced the wire nuts with 3 Port Push-In Wire Connectors, so much easier and faster then trying to twist 3 wires together and using wire nuts. I Reconnected the battery, plugged in the 120V, inserted a DVD and in seconds had a movie playing. Wonderful.
