Large GPS dash mounts

I have a large class A MH and I was recently given the Rand McNally RVND7710 gps. The unit came with a windshield mount, however when mounted on the windshield it is way to far away to reach it. Has anyone found a system that will allow you to mount it on the dash? I know the unit is heavy and the usual bean bag mounts won't support it. I wish the manufacturers would have thought of this problem before releasing it.. Can someone please help!

The Good News .... There is a magnet mount unit on the market that allows one to attach the magnet to the dash and then the suction cup part of the windshield mount attaches to a shiny smooth piece of circular metal that comes with the magnet and that lets the unit be placed in front of and comfortable to the driver.

The bad News ..... I don't remember who manufactured it but they were in the RV accessory aisle of a DIY store here in town.

Tony, we install ours by turning the base and attaching it to the driver's side window.

There is one available that has a adhesive back and a metal disc on top for the suction cup. I have one that works well only because I can rest the GPS on a hump on the dash. Otherwise the GPS is just too heavy

I have the similar Magellan and didn't like the mount. It was too large and moved around too much. I bought an aftermarket window suction mount and mounted on the passenger's side window where my wife can operate it. It could easily be mounted on the driver's side window too.

I may have a solution for you, will know in a week or so.

I am replacing my dead OEM GPS on my Vectra with the 7710. In my cab the old GPS was an Alpine DVD unit in the overhead and a 6.5" monitor mounted on my dash. I think I've found a way to mount the 7710 in the flat spot where the old monitor stood. It involves a round ball base for the dash, another for the GPS (I'll call it the 'backplate' - the holder part that the GPS snaps in to and has the stylus on the back), and a double-socket arm between the two.

I went here RAM Mounting Systems, Inc. and after looking for a while and taking some measurements I've ordered the following parts:

RAM-B-202 Round base 1" ball AMP hole pattern
RAM-B-201-C Long Double Socket Arm for 1" ball bases
RAM-B-238 Diamond base with 1" ball

I have measured and believe the diamond base will fit nicely into the removable backplate that holds the 7710. I'll either have to glue or more likely drill/countersink a couple small holes in the backplate to mount the diamond base. The larger round base will fit my dash and the double-socket arm should give me a wide range of motion.

Warning: first, I have the parts on order as I post this, but it will be a week before I get them to know for sure if this will work. Second, attaching the diamond base to the backplate will make it unusable in the suction mount while the diamond base is attached.

I'll post more when I get the parts and see if it works out, but with the link you might find some options for you.

Where did you get this specific Bean Bag mount? I have the same issue being discussed and this looks like a nice solution.

Walk into any Best Buy, you'll find several options. I have the same GPS unit and found a thin 'rubber' mat, maybe 5" by 6 or 7", with a 'sticky' silicone or rubber on the bottom side that keeps it in place (but is easily removable should you want to) and a smooth disc in the center that the GPS mount sticks to.

I had a particular problem in that the dash in front of the driver was angled down at a rather steep angle.

I took a piece of 1/4" plexi-glass about 6"x9" and heated it about 3" from the end making an angled piece about 6 x 6 & 3 x 6. I heated it initially with a hair dryer, then finally, very carefully on the stove top over a burner. I finally got it the correct angle, sanded the corners and edges, then pasted it to the dash with double stick foam tape. It works pretty good!
