I poked around on RV Trader and it looks like the 29MVs used a camera that's different from the one on our 2016 31FK.
No surprise - Jayco probably just sources whatever is instock and convenient. But, that also likely means the connections are pretty standard.
I'd bet dollars to donuts that something like this (which is what is on our 31FK) would connect right up:
If so, a $11 eBay special would allow you to make sure it's replaceable:

I get it, you'd like to just have the one that's there work properly.
But if you decide you cannot make it work and need to swap it out, I'm thinking it might not be a big investment.
