I'm pretty sure that the system in a View is a "double DIN" sized "stereo." And, that any Car Audio Installation shop can replace that unit. But the tricky part is finding one that works with your cameras, etc.
Hopefully someone will chime in here with info about choices they've made and how they got everything to work.
You might try searching on www.irv2.com
. I know that the Xite system comes on many RVs from many manufacturers and this subject has been discussed at length over there.
Keep in mind the Xite platform is NOT the same on every RV. So, what works for your View won't apply at all to RK911
who is watching this thread with a Suncruiser 38Q.
It's best to learn your system's model number and start with that info so that you can find the appropriate infotainment system for your RV.
