Bill,
Here is the information that I received from Girard regarding the motion sensor upgrade, the price is three years old.
Yes, you can upgrade to the motion sensor system. Is you coach pre 2012? Does it have LED’s on it?
You would have to purchase an electronics upgrade kit,
98GCK-19 Single Awning Electronics Kit w/ 12v Motion Sensor (Motor Control, Remote, Wall Switch, 12v Motion Sensor. $959.00 + shipping. In Stock
If you don’t have LED’s then you want to specify to include the wiring harness with the motion sensor so you have the wiring and parts necessary to run a wire down the motor side arm to the lead rail for the sensor. The sensor hooks up to 12v constant power and communicates wirelessly with the new control box.
So, all that would be left is labor to install.
