Good GPS for Class A motorhome

I just changed out my old Cassette/CD/AM/FM radio for a new JVC stereo with Apple Car Play. I just did it yesterday so I haven't had a lot of time to play with it yet, but what little playing I did do, I like it so far. You plug your iPhone in and it displays your iPhone on it's screen. Or at least it shows the iPhone apps that you can use while driving. I do have Waze on my iPhone but I haven't checked to see if that works yet. The regular Google maps GPS works great. And you can use iHeart radio at the same time which is great since I've always had a difficult time getting a good radio signal in the RV.
