Garmin reversing cam and sat nav kit removal

Hi all

Has anyone undergone the process of removing and installing an alternative reversing cam system/ in their PVC - I have a 17 Fairford. I have seen one offered by Roadpro -
Camos Jewel Plus V2 Camera with Cable & 7" Mirror Monitor   in their van - expensive but i am fed up with the hit and miss quality of the current van Garmin   I am wondering if there are any known probs / issues with the current van layout etc ie wiring and retrospective fitting
Many Thanks

I had the Wi-fi one removed from my 2017 Stanway and replaced with a hardwired one that I could have on all the time, not just when in reverse. It was done at Derby Motorhomes where I bought the van.
I understand from the fitter that the most difficult part was getting the camera out.

Thanks OAPtraveler-  That gives me some hope
