My Rand McNally RVND 7730 is no longer supported. The USB power cable connector broke and was no longer supported. The GPS rides on a sliding mount and the cables for power and the backup camera snake under the dash panel and I had no idea how to move forward other that I needed to remove the dash panel which was not obvious.
Nicolas @ Winnebago customer support provided me with the Dash Install drawing 30245201000 which was a real help. But it did not tell the whole story. The following is what you need to do to remove the dash platform and obtain access to the cables and the cable chain/raceway. Also very helpful was Cortona3D Solo Universal Viewer which shows a parts breakdown.
1. Remove the air vents on both sides of the dash. Remove the housing from the flexible hoses. Remove the two screws holding a bracket on each side.
2. Remove the instrument cluster housing.
3. Go outside the MH and open the engine compartment. There are four nuts in the front of the engine compartment ceiling. They are covered with a tar like material. Remove the nuts.
4. I removed the side trim on either side of the windshield, but I may not have needed to.
From here is the scary part. Lift up on the center of the silver trim on the dash platform. The platform is held in place now with a lot of Velcro strips in the dash frame. Work from side to side and front to back repeating until all of the Velcro is free.
Once free, the dash panel can be raised and you will be able to access the cables, GPS mount and the chain/cable race. I removed the mount, chain and cables. I wil be installing a new Garmin GPS and a Bluetooth backup camera.
Hope that helps the rest of you.
