I use my phone mounted in a holder on the dash [https://amzn.to/3pKIHU
G] just to the right of my field of view. The GPS on my phone is way better than the Soundstream system that is installed in my Greyhawk.
I also put a HUD https://amzn.to/397fA8e
next to the phone so I could see the speed and other information without trying to look down through the steering wheel. When it's windy this RV needs my eyes glued to the road ahead.
I like the idea of the camera feature. When I am turning right I can see the display as I am looking in the direction of the right mirror.
When turning left it is useless as I am looking left and the display is full right... its actually dangerous IMO.
I wish I could use the cameras for other purposes like to see cars in the lanes on the left and right. I often just turn on the blinkers briefly just to use the camera on one side or the other.
It does take too long for the camera to turn on.
I wanted to hack the setup some way to enable the cameras when underway (like you can do with the rear camera)?
Initial research suggests that they are connected through a serial interface with the steering wheel controls. Uggh!
