Has anyone found a way to attach the suction cup holder to their windshield?Normal suction attachment fails with temperature change. I have tried taping the suction cup to the windshield with plastic tape, or Gorilla tape with tape eventually loosing adhesion due to weight of unit, vibration, or temperature changes.I am thinking of super-gluing the cup to the windshield as a last resort.:M

Please dont super glue anything to your windshield. There are PAGES and PAGES of various GPS type car mounts on Ebay. Find an alternative to the suction cup if its not working for you.

Ditch the suction cup. They age too fast sitting on the glass and will not hold for very long, even if conditions are perfect. I have one spot under the windshield glass where I have permanently adhered a pad of 3M "Hook and Loop". This is similar to Velcro in concept but is much stronger. The hooks and loops have a very positive hold. I use this pad for GPS antenna or anything else I want up there. I have door-mounted audio tweeters, they are also adhered with this material and they stay in place through many door slams.

Cleaning good with alcohol wipes helps somewhat, then clean it each time you remove and replace. The changing temps will harden the seal, and it does need to be removed and reset often. Also, be sure and clean the little circle off the glass whenever you remove and store the GPS. The little circle is a sure indication to everyone that you have a valuable GPS in the vehicle. You could end up with a lot of broken glass even with the GPS hidden.

Johno2 is correct. Make sure you are cleaning the windshield..alcohol.I have one of these. It has not moved in over a year. Very solid.Suction Cup Mount...LINK

Some suction cups are much better than others. But a clean suction cup and a clean glass is your best hope.If a GPS, I much prefer the beanbag type dash mount to a suction cup mount. Down low out of line of vision, and easy to move to floor out of sight when vehicle is parked.

Thank you guys:

In my Class C, the upper left corner of the windshield is by far the best location for a Garmin Nuvi 2589LMT. The unit is out of the way for vision but very reachable for use. I have always used the method of cleaning window and suction cup before each use.

Believe me; there is nothing worse than having the unit come loose and be hanging in front of your vision since the cords feed over the visor and rear view mirror to drop down to the 12v power outlet.

I lick the cup then put it on the windshield. Gross but it works.

My gps has a mount with a suction cup base that "sticks" to a suction cup disk mounted on my horizontal dash. Periodically it lets go. I simply clean the disk and the cup with eye glass cleaner. I then spray a little of the cleaner on the disk, put the cup on the disk, give at good swish around the disk and then engage the suction via the lever. Sticks great for quite a while. The key IMO is clean on both surfaces.

The dash mount, as opposed to the windscreen mount, puts far less torque stress on the mount bond. A permanent mount to the windscreen may be a problem in some jurisdictions that ban mounting anything to the windscreen. I understand that this ban exists in CA.

I have NEVER found a suction cup that stays on a windshield or the dash.

I use the donut holder on the dash. It stays where ever I put it.

I can also move it around depending on how the sunlight hits it or where it's easier for me to see day or night AND I can just grab the whole thing when I want to move it my toad or someones else's car. And when parked I just grab it and put it on the floor so it's not an invitation to thieves.

Putting a little water on or licking the cup does make it seal (therefore hold) better. The problem is that the water eventually evaporates, especially in hot weather. Putting a little (very little) vegetable oil on the cup will last a long time without drying out.

Just make sure it's extra virgin olive oil...much better, healthier, and legal for use on suction cups in California.

A dab of clear Silicone sealer in the middle of the suction cup worked for me.
