Re: suction not holding on window

Hi I had this problem myself - other than going to the expensive option of getting a new suction cup, inspect the existing one carefully, and if here is no crack or break in the cup the problem could be caused by some slight distortion of the suction cup caused by it resting on other items in the glove box or similar. the distortion does not need to be much to stop an airtight seal. Here's the solution: Get a bowl of boiling water, soak the suction cup part of the cradle in the boiling water for a few seconds until it goes slightly soft,  remove it from the water and quickly, dry the part. Next quickly (whilst the plastic is still soft) apply the suction cup to the windscreen in the method indicated by the manufacturer -and that is it! The water softens the plastic so that it can be pulled into place by the vacuum of suction cup mechanism.  
Hope this is of help to you or anyone with a similar problem

Re: suction not holding on window

There is a handle which tighten and release the suction cup. Release the handle, wet the suction cup and position the unit onto the windshield and move the handle to the tighten position. If you are trying to just stick the unit onto the windshield, this will not work.

Re: suction not holding on window

I suggest that you clean the surface from particles and when its already clean, try damping it with water, but not too much.

hope this helps.

Brian - you should contact Garmin directly at - this site is not affiliated with Garmin in any way. I'd suggest that you secure the GPS to the center of the windshield or use the semi-permanent dash mount instead of suction cup mounting to the windshield near the driver window.

Good luck!

This is a fairly common issue especially with aftermarket tinted car windscreen 'film'.
You can try prolong the suction by wetting the suction cup with water of very slightly soapy water before applying it to your 'clean' windscreen area.
As for the dashboard, for some models, TomTom provide a plastic circle to which the suction cup attach to. The plastic circle is first 'permanently' attached to your dashboard with double-sided adhesive tapes.
Hope it helps: let me know how you go.

Plastic pholder for my Garmin 255W will not stick to windshield

The glass and attachment suction cup should be clean and free of oils, dust hair etc. Try cleaning both surfaces. If this doesn't workyou can order a new holder from Garmin.

Sticking my nuvi 260W to windshield - after a few days often in sun [winter/spring Mass.] thesuction cup mount falls of to dashboard- risking damage to nuvi. advice? without having to use permanent...

Here is what I do. I clean the spot on the windshield very good with Windex or another good window cleaner. I also clean the suction cup surface while I am doing the windshield. Next I place the GPS next to the Rearview Mirror. and connect the suction cup. Then I take the power cord and use it to tie a knot around the suction cup mount and then I loop it around the Rearview mirrow twice leaving no slack between the GPS and the Mirror. Be sure to not block you view in the mirror. If the GPS come loose from the windshield it will just fall far enough for the power cable to catch it and will just be swiing there instead of falling to the dashboard or floor. This is kind of a Mickey Mouse way to do things but it works.

LG GPS not suctioning to windhield

You must clean the window area using windex, or other cleaner, and wipe until dry. A clean winshield area provides the best suction, from the mounting bracket.

Slide the mounting bracket switch to Off & On a few times, make sure the suction cup is able to move(slightly) and that the small tap is facing the area with the notch in the metal.
After putting the switch to the middle, moisten the suction cup slightly
(saliva works bestter than water for some reason)
press it to the window with a slight amount of pressure
then move the switch, (Which should be set to Center!)
to lock it on firmly.

If this doesn't work, then there is a good chance the suction cup has become hardened by the sun. If that is the situation, you'll have to contact LG
(or a place that sells "knock off" brackets to get a replacement.)

I never leave my LG GPS in the car, when not in use. Even the bracket comes out, as I've seen what the sun can do to damage those plastic suction cups, fortunately, I learned it on a $5 replacement set for a Radar detector/Emergency Vehicle Alert device, and not a more expensive bracket.

Suction cup problem

Make sure your windshield and the bottom of the suction cup is clean. Clean it with some warter & detergent and wipe dry. Try wetting the bottom of the suction cup before applying it to the window.

I recommend not using the window mount. I recommend using the dash friction mount. You take the risk of cracking your LCD screen when it falls.

1. The dash friction mount will not fall.
2. It's easily removable/
3. It's legal in all 50 states (window mount is not).
