Has anyone else had this?
Sticky pad falling off the GPS unit dropping the camera, but the pad remaining firmly stuck on the windscreen?

This is the one spare sticky pad, as the original one on the GPS unit also did the same.

You can simply replace the tape with some fresh 3M VHB tape. Unfortunately, dash cam adhesive does fail like that from time to time. Perhaps it was not applied correctly or under the best of conditions?

You can find replacement 3M VHB tape on Amazon. If required you can simply put two or more strips side by side to cover the entire camera mounting plate. 50mm wide tape is available but not always easy to find. Make sure to thoroughly clean both the glass and the mounting plate with ispropyl alcohol before applying new tape.

I have run into the same problem a few times over the years, always with cameras i have moved, the "funny" thing is it is always with the camera plastic that give up, it is never the bond to the glass of the windscreen.

First time i tried cleaning the otherwise clean looking surface, that did not help, then i tried cleaning and then sand the surface clean with 1000 grit sand paper, that also did not work.
So in the end i got POed and just put some CA glue on the mount and then stuck that to the pad on the windscreen, and then the damn thing stayed in place.

I dont know why it is like this but i have tried it several times, and its just like the contact surface on the camera / mount do not work any more, but it is fortunatly on the disscardable side of things so i have no problems adding a glue to help things along.

You are right about the tape often falling off the plastic rather than the glass, @kamkar. On a very hot day, I came back to my truck and found my rear camera hanging down by its cable. It fell off the plastic side, of course, and the tape was still attached to the glass. There was nothing I could really do about it at the moment so I just pressed it back into place until I could get home and do a proper repair. Somehow, I didn't get around to dealing with it but the camera stayed put. Eventually, like two weeks later I figured that I'd better do something about it or the camera would fall off again, so I went to my driveway with plans to take down the camera and replace the tape. Well, the thing is bonded on there so well that I can't easily remove it now. Go figure!

This is the one spare sticky pad, as the original one on the GPS unit also did the same.

This generally happens when you don't have a good bond between the two. If you have alcohol pads, be sure to clean the windshield very well. And also make sure the surface of the GPS Mount is clean. You can wipe with alcohol pad, too.

Attach the adhesive pad to the mount, and then firmly press it onto the windshield. Holding it there, applying pressure, for about a minute or so, to create a good bond. I've never had an issue with mine coming off. Matter of fact, I've had more issue with trying to get the damn thing to COME OFF when I need it to.

May I know How long have you used the sticker? How's the temperature outside?

Do you mind we send you a new one?

Ther original sticker lasted 4 days before failing, this spare one around 2 weeks after cleaing the orginal off and wiping down with alcohol.
Outside tempurature was around 18c.

I'd happily accept replacement stickers.

First time i ran into the issue, was installing my Lukas LK-7500 in my sisters car.
First i tried the spare pad from Lukas, that failed, then i tried a spare patch from a SG camera, this also failed, then i tried a #3 3M patch ( unsure of brand ) anyway it also failed.
And then i got mad and brought out the CA glue, and then the sticky pad did not let go of the camera plastic mount / base.

To be honest with that i have tried when it have happened to me, it is like the things are under a spell, cuz i can not see any good reason as to why the sticky pads should let go of the camera ( always made sure things was in order, i dont just put a new pad over goop from a old pad, every time the surface have looked clean or been cleaned vigorously with solvents that have worked for me in other scenarios.

BTW i have also now seen cameras come off the glass, but this is due to me mounting where other cameras have been, and all of the residue not been gone as it is impossible for me to get all off, but cleaning properly in my case with Kent Speedy 500 ( glue remove solvent ) have fixed the problem, at least the 2 cameras i have put on the glass since the cleaning have stayed in place.

But even with speedy 500 i cant get all of the goo in the perforated shaded area on my windscreen ( most cars seem to have a dot array there for shade but mine have a grit like the leftovers from other cars have been used in my car, so instead of dots o have a grid with round holes in it.

I should probably also say that the K2S camera units ( side cameras ) on my rear door fixed glass are threatening to come off, but have not so far, but it look close some times when half of the contact have been broken.
They have been there for 2 years now.

Use some detergent, I suspect that some batches of plastic leak some oil, and the pads don't stick to oil. Seems to be a very occasional issue with many brands.
