The Kenwood works great, including BlueTooth. I don't use the pay apps that are built in, but it has several: Pandora, Aha, Sirius... It has a front & rear USB, and a mic with a cord long enough to easily reach the RV mirror. Backlight color 15 is closest to the factory dash color.
I haven't decided where to put the switches yet, or which style to use, but the USB power jacks below the radio, & another pair inside the dash, will be switchable between OFF, key-switched, & always-on.

The
Cobra 75WXST was quick & easy to install. Running the antenna cable took longer.
