What is best way to firmly affix a Garmin C340 in a rental car?

You can get the Friction mount from Walmart see http://www.walmart.com/catalog/product.do?product_id=4232210 . I starting using it after a problem with suction cup.Very happy with the friction mount.Drove from Florida to VA with no slipping problems.

Here are a couple beanbags from Radio shack.

Another vote for this mount. My Dad has this one and he has not used the windshield mount since he's got this.

The dash mount is the best way to go.

I use that mount exclusively in my own cars and in rental cars when I travel. Its easy to move from car to car and you can slip it off of the dash and out of site in an instant. Also on some cars, it sets very nicely on the console out of sight, but still easy to read.

I got mine off of eBay.

You can also try this mount.

It just came out. Hey, it has different holders for different brands.

That type of holder is great but I believe the this wouldn't be practical to travel with. The OP stated that he wanted something to use in rental cars and the size of this makes it somewhat impractical to travel with......especially now that airlines want to charge for checked bags. We who travel need to keep things down to minimalistic size. I personally just wedge the original suction mount into the corner of where the dash meets the windshield and haven't had any problems in my travels.

walmart has a mount that just sits on the dash the weight of the mount keeps it in place works great cost is somewhere around $25.00 to $35.00 .

Wet your finger or apply a small amount of moisture to the suction cup. Then fasten it to the window.....if will not come off!

Recommend the following: "Take your navigation device with you while driving with this quality friction mount from Garmin. Requires no installation and is easily portable from vehicle to vehicle. With a protective, non-skid base. Inlcudes cigarette lighter adapter. Compatible with StreetPilot c320/c330/c340 GPS units."

Cost is $29.87, weighs: Shipping Weight (in pounds): 1.35

I tried about every thing and this friction mount made me a happy camper again.

As previously stated, a little moisture applied to the cup, and when I flip the lever its stuck till I remove it...

The beanbag or friction mounts are great itdeas for temporary installations. I have a Nuvi 660 that's "permanently" installed via a steel bracket connected to the dash near the radio. Try http://www.mountguys.com/ for some great options.

Thanks to everyone for their feedback. I ordered the friction mount from Wal-Mart. I think that will work well with the rental cars I use each week.

ranlay. Walmart has larger camera bags that work well with this unit.I can put the gps and friction mount plus all the other accessories with it for easy transporting.

I just looked and Amazon has the WalMart style dash mount for $30.22 delivered. It is advertised for the C 3XX series but I assume it would work equally well for the Nuvi. Can someone tell me if this is this correct?

Terry

I don't believe it will if is the same one at Walmart. This one shows for Nuvi models http://www.walmart.com/catalog/product.do?product_id=8154370

Thanks Charlie. I use the one you referenced for both my Nuvi 350 and my StreetPilot C530. Wow, Walmart is priced much higher than Amazon.

I have the Bracketron like the one at the above link on Radio Shack and it works great. But Amazon sells it for $11 and change, much, much cheaper

Amazon has good deals on some products.Most times Walmart hard to beat but not in this case.

The bean bag is the way to go. Simple and quick.
