Just worked for me with my hair dryer. Took maybe 4 minutes but be sure to clean everything first, Thanks for the tip.

This idea works!! I did it and it made a big difference in the suction cup staying put. Lots of other people have ideas, but your idea is the real fix. Thanks!

I'm excited to try this with my turtle dock. I must admit the real reason I wanted to leave a comment is your voice! The tone has such an soothing warmth - Intoxicating!

mate you're a legend. I've been trying to figure out why it happens and I thought it had something to do with the spring!!! didn't notice the rubber part!

Cool video. Thanks for sharing your procedure.

That is a great tip.- After trying lots of things I discovered that where the soft and the hard plastic meet, there was a almost invisible tear in the soft plastic where the air would go out (in, actually:) straight away. A bit of superglue helped a lot already, now for the finishing touch I´ll try a hairdryer.

This worked perfectly. Many thanks. For those that will do this just take your time and monitor the heat applied

Excellent - worked with hair dryer- many thanks for sharing

Thanks for that first class video.

Worked as advertised.....Thank YOU!

Thanks mate. Worked a treat.

The heat warped the plastic a little, but the suction works again. For now. Will have to see how it does later. Thanks for the advice.

This works. Be sure to clean the area on the windshield as well. It will have a thin film in the area. I used baby wipes and my fingernail as to not scratch the glass. It can take a little while bit it's worth it. 👍🏻

Worked perfectly! Thank you!

Its easy to take the pin out (I used a meat skewer from the kitchen drawer) and separate the parts. easy peasy. Then you can hold the rubber (and a little plastic part) over the gas burner for a minute or two. But there is probably no need. THE PROBLEM IS THAT THE RUBBER BECOMES POROUS. I got some furniture polish and rubbed in at least two layers into the rubber with my finger. That fills all the pores and creates a proper VACUUM again.

Ha, you da man! I would also like to add if I may, That whoever performs this method first wipe the entire face of the suction cup with denatured alcohol and a clean cotton rag prior to applying heat so it’s not too enbed any pre-existing dirt particles into the soft rubber, followed by a application of vinyl dressing (armor all) after it has cooled.

Heat gun trick worked. I also use water based glue as well. Lots and lots of it.

Cool... I didn't think of using my heat gun. I rejuvenate suction cups all the time by dropping them into boiling water for 30 seconds and then dropping them in cold water to cool fast but, it didn't work for this suction cup. Problem solved. Thanks for your post.

Good advice I'll try it. Could not hear you talking when the dryer was on though.

*Fantastic fix! Used a hot air gun on mine for about 3 minutes, it almost completely flattened out and is stuck HARD to my windshield again.*

thank you SO MUCH!! I hit the subscribe button..

Great idea! But, I tried hot water and it worked great!

Thanks for your video will try

Brilliant! Thank you!!

That’s brilliant… thank you.

I like this guy thanks for sharing

Lighter works well also

I guess between the sun and temperature variations that’s what deforms the suction cup? Guess I’ll be doing this every 6 mos or so? Thanks for the vid!

Thank you!

I have cleaned both my suction cup for my Garmin and the sticking surface with glass cleaner with no luck. I might try this trick when I get the chance.

Thanks for sharing...

Thanks!

A hair dryer did work! Much obliged.

LOL!! you're awesome!! trub is mine i went to touch the plastic bit an it just fell apart!! so now stupid navman dont sell the MIvue 530 and I'll be stuffed if i will buy a new dashcam just because navaman dont have the same mounts for all models!!

I will try. Here in Florida sun they don't last long.When this works I will just release the suction when not in use and let is lay on the dash until needed. Should last longer that way. Oops! Mine has a crack in the rubber suction cup so need to order new one. Did learn to place mount in holder as it get too hot for fingers. Also found after heating I could hold down the edges with my fingers and plunge into bucket of cold water to retain the new shape.

Awesomeness

Thanks

I tried it, but stopped before it went completely flat. I could tell the difference on the first use. It just felt more secure and held so far without fail.

good tip

Any idea on how to keep the ball part stiff, that has become loose over time as well and everytime I play music my sub woofers make it slowly angle down

Putting the suction cup in hot water (until boil, then remove heat) for 10 minutes or so also works well (for all kinds of suction cups)

Don't know if the material used on TomTom suction cups is thin, but I used a heat gun for less than a minute and it cracked the material where it connects in the centre and deformed in another area beyond repair.

I did not mount mine on the windshield...I mounted it on the dash just above where the console meets the dash front...its perfect and I dont ever look down when i'm driving I pull over If i need to type info into it or do it before I leave to where I am going. I mounted it with double back tape on the metal part of the dash in my truck! No probs for two years!!

One piece of missing information is what temp the heat gun was set at. Please provide. Thank you.

I noticed my GPS suction cup falls off during cold times, so I wonder if the temperature has something to do with it.

I have the Exact same Wagner Heat Gun, did you use low or High setting? Thanks a bunch! GREAT VIDEO!

Did you have to do this every 3 months or so?

Gee thanks!

Glue works to

do you think the heat on our dashboard on a hot day would produce enough heat to reshape the divot also? a thought for those without a heat gun or hair dryer. supposedly we can bake cookies on a hot day.

mine has the opposite problem. It turned to liquid, now it's surface is all gooey and deformed. I think it's from my anti-fog or something

Tried a hair dryer, failed to get the "divot" out. Bought a heat gun. Heated the suction cup until it was completely flat. Attached it to my windshield. Hit the bump at the bottom of my driveway. GPS is on the floor.

Great 👍👍👍👍👍my dash cam keeps falling off my window.

heat gun. video done.

Safer way is to dip it in boiling water for 2 or 3 minutes.

Black screen - can not see anything?!

My dashcam mount ruin thanks to this tip. Don't try it

Thanks
