TomTom One - won't stick to windshield

I didn't have very good luck with my 720 mount sticking to the TT supplied disc, that I mounted on my dash. I bought a mount that attaches to the dash A/C louvers. It does quite well.

Inspect it for nicks, cuts or debris on the surface.
It wasn't exposed to high heat while not in use, was it? ......so that it might be badly warped?

Then try cleaning the cup with mild soap and water and then moisten is slightly when used.

Is the mechanical lever part working correctly?
You do know that you have to push firmly while latching the lever, right ?

It was brand new, taken out of my drawer so it was in perfect shape.

It has a twisty knob that shows lock / unlock. And I twisted it to the lock side until it won't budge any more, and it will not stick at all, even when pressing against the glass.

It's strange how it won't stick at all.

If it doesn't work, then I guess it is NOT "in perfect shape"......for whatever reason.

seeing as how it's against the law to suction cup anything to a windshield out here in California.

I've had to hassle with my mount as well this winter. I found that when both the windshield and the suction cup are cold then suction is almost impossible. I've had better luck after warming the windshield (defroster) and the suction cup (heater).

I have a 2 year old One so the mount has been around the block a few times!

I thought it was legal now in California to mount your GPS to the windshield, as long as it is in a certain area in the corner?

You can find generic mounts that may work better. See http://www.gpscity.com/gps-mounts

Same problem I first had with my new One 125 suction mount. I fixed it with the following 3 steps:

1) Unscrew the knob all the way counter-clockwise.
2) Wipe the suction-cup clean with MIST (moist spit).
3) Push on window, turn knob clockwise, and viola!

Worked ever since. No problems. Maybe the suction cup was coated with a light layer of "vegaline" or something like it to keep the rubber cup from drying out, and also which keeps it from working properly. It's the same goop they put on new car paint to protect the finish prior to shipping it.

I also find that by wetting the edge of the suction cup with saliva it sticks so much better.

I had the same problem with the mount that came with my GO 930. I didn't really like having it on my windscreen anyway, so I purchased the TomTom gooseneck and a Nav-Mat (like a bean bag) mount to place on my dash. I like that option better because it does not leave any tale-tale marks on the windscreen (letting would-be GPS thieves know you have one). It also gives me more flexibility about where I can put the GPS. I only use that option for long distance trips. For traveling around town, my wife made me a beanbag that I place in the cupholder and set my GO 930 on it. It keeps it in place & I can easily see it out of the corner of my eye.

Agree that TomTOM neeeds to make some modification ot their mounting product. Winter is an issue. Thanks for the gooseneck idea, I am going to pick one up.

Is it convenient to stick in a briefcase? I fly and rent, and bring my GPS with.

IIRC, in the lower right or lower left in an aprox 5 inch square area. Pretty much close to impossible to utilize your gps device effectively. Typical political response to a non-problem.

Law has changed and I did not know. Here are parts of the Section:

26708. (a) (1) ( )1 A person shall not drive any motor vehicle with any object or material placed, displayed, installed, affixed, or applied upon the windshield or side or rear windows.

(2) ( )1 A person shall not drive any motor vehicle with any object or material placed, displayed, installed, affixed, or applied in or upon the vehicle ( )2 that obstructs or reduces the driver’s clear view through the windshield or side windows.

Update:
(12) A portable Global Positioning System (GPS), which may be mounted in a 7-inch square in the lower corner of the windshield farthest removed from the driver or in a 5-inch square in the lower corner of the windshield nearest to the driver, if the system is used only for door-to-door navigation while the motor vehicle is being operated and outside of an airbag deployment zone.

I read this as: as long as it's not squarely in the middle of the window, the LE are not going to bother you.

I travel frequently also. I disconnect the gooseneck from the Navmat then place both of them along with the GPS in my laptop bag.

Thanks for clarifying that tsunami. I wasn't sure. Still has to be pretty far from the driver though. A friction mount sounds like a better bet.

What I don't like about TomTom is that they sell an expensive G930 GPS unit and they provide a CHEAP friction mount that's too short (i.e. too low) to work effectively with a bean bag. Why can't TomTom supply a similar friction mount like Garmin does which has a lever that you can pump several times to expel any trapped air and then push down to provide a really good vacuum suction? TomTom's cheap friction mount is 1" too short to work well with a bean bag and its friction mount must be pushed extremely hard on the bean bag base and rotated a few times before it will stick and then about 30 minutes later, it becomes loose and flies off the bean bag when your car takes a sharp turn! LOL!

Spray a bit of hairspray on the back before applying to the windshield.

I usually just set my GO 930 on a bean bag and place it on the center console. I give up a cup holder, but it is out of the sun and easy to see out of the corner of my eye.

My Garmin keeps falling off the windshield and setting off the alarm when it hits the dash!!!

I've owned a TomTom and had my windshield smashed for it. But before that day, I also had many problems mounting mine. I think all the TomToms nowadays come with the threaded twist-knob suction. I don't really like them either. The garmin ones work slightly better, but still fall off.

I find the problem is that if both the suction and glass aren't perfectly clean and there is room for air to escape, it will fall off almost always eventually.
I can't mount to my dashboard, as it has little cracks in the finish that will not allow suction.

From my own experience, when i apply the suction cups (both garmin or tomtom) onto the back of the stickers on my windshield, they actually provide better suction than the windshield itself. Why? I don't know, but it has been working for me (Also doesn't leave circle marks on the glass!).

I find that the bean bag things work the best, but are very bulky. There really should be a better solution to this without all this extra effort...

I've never had any issues with my Garmin mount. A few weeks ago I had an accident, a guy blew a red light & hit me in the front part of my driver side door. I had my top down & the car had to be towed but my Garmin & mount stuck to the windshield like glue. I, of course, took it off before the car was taken away.

I never did anything special to it, not even the spit thing. My Dad, on the other hand, has a TomTom & can't keep that thing mounted to anything.

Don't trust the suction cup! Mine dropped my TOMTOM on to my gear shift... the screen got cracked, and so did my temper.

I got a beanbag mount... and I used Velcro to attach the cup to it. NEVER has this moved from my dash!

This mount is only $20 us at Amazon.

Thanks for the info.

I have mine for years, it's been working fine, freeing your dashboard from clutters ..!

I have had the suction fail on my girlfriends mount as well. Usually over night sitting in the garage.

Compared to my suction cups on my Valentine One Radar, the Tom Tom is a godsend.
