Confusion on replacing 2015 Thor Ace jensen radio

[GaRVLady]

We have a 2015 Thor Ace 27.1 with a Jensen JRV212T radio, which displays the rear view camera and the mirror cameras. As I am looking for a replacement radio is there a way to only see radios with the duel mirror and rear cameras. Or what radio have you choosen that does the cameras.

The radios only have a single A/V input (for a back up camera). The switching between the cameras is done by an external switchbox. So any radio with an A/V back up camera input will work.

Thank you. I did not understand that.

Maybe: Some Jensen radios had 3 inputs (the JRV-212 and JRV-215 come to mind).

You used past tense, does that mean new radios expect the extra connection box and only now come with only the one rear camera input? If so where would I find/get the junction box? And what special wiring would I need?

I think first I'd want to find out if my RV has a junction box already. I know on the Axis/Vegas units the junction box was under the removable panel above the dash (two 1/2 turn thumbscrews and the panel comes out). Not sure if other Thor A's have such a panel or not.

Do you know your Jensen's model #--you could google that and find out pretty quickly if it has one or 3 inputs.

Here is an example of a switchbox, although at $89 its a bit pricey:

This one is far less expensive ($29) but it doesn't have the trigger inputs to switch the video based on brake and/or turn signals--but it does have a remote:

and, finally, a $26 one that may work:
