I posted this on another GPS forum and thought I'd share this with you as well. I have come up with a fix for the terribly low volume on some Tomtom ONE 100/300 series. It is as follows:

NOTE: This procedure is followed at your own risk. I take NO liability for damage, etc. Also be VERY careful with the tabs on the speaker grill. They break very easily. And lastly, the metal tabs that hold the mount on are located around the speaker. Make sure you haven't disturbed these in the process. If you do, they WILL pop back in after some finessing, but can be a pita. I found this out the hard way


First: This may have been posted elsewhere, but search isnt working correctly for me and I couldnt find anything. The only thing I found was the "beating method". So if this is a repeat, feel free to call me names. :D

At any rate the low volume condition in the Tom Tom Go 130S is due to a defect(easily fixable) with the speaker. The "cone" material is made of thin plastic and apparently at the factory, the cone got pressed down and got stuck. All one needs to do to fix this is remove the silver grill on the back with a combination of flathead jewelers screwdriver(to pry the initial tab) and a larger flat head to GENTLY pry the remaining tabs.

Once the grill is off, the speaker is free to be massaged. You should see the black plastic cone and how it is compressed to the spider. Now just take your finger and rub in a circular motion to free the cone. You should feel it snap into proper place. NOTE: Be VERY careful with the speaker, the wires are SUPER small and can easily be broken. Once placed back into the unit, you should notice a tenfold increase in volume and clarity. This unit is easily louder than my previous Go ver. 3 and louder than most Garmins I have heard! Hope this helps.

Hey, Great advise! Here is another happy person. My father in law had the same problem: suddenly hardly any sound from the TomTom. he was very sad because he cannot hear very well and he is very dependent on his TomTom for driving.

I did take your advise and followed your instructions. Guess what: in 15 minutes (I was very carefull removing the grill) I fixed the problem and now it sounds like 10 times as loud.

Thank you for posting this instructions.

You're more than welcome! Glad to hear my post helped and thanks for adding a fuller explanation!

I guess your guess is incorrect

I searched for exactly this answer and thanks to YOU and your detailed description of the problem I managed to fix TomTom One for someone in less than 5 minutes. I suspected something like this but first wanted to have confirmation that no software/firmware was at fault before digging into the TT as this unit is 3 months old and still under warranty.

The explanation for the low sound is actually simple:
the voice coil is attached centrally to the underside of the plastic cone that when displaced from its original position leaves the coil away from the magnet. This additional distance from magnet's gap lowers in turn the strength of the magnetic field surrounding the coil to such an extent that interaction between the magnet and the voice coil is only a fraction of that when the coil is fully submerged in the magnetic field around the magnet's gap. When the coil is back in its proper place (well within magnet's gap) the coil actuation by electrical signals fed to the coil is of much greater magnitude than when it is displaced away from the magnet hence producing MUCH louder sound.

My last explanation of why the coil might get displaced in the first instance is that I suspect when the unit is accidently dropped from a height it falls on the speaker silver grill side due to its centre of gravity shifted towards that side due to significant mass of the speaker itself. This causes the plastic cone (and the coil with it) to become displaced on impact and it has to be ""helped"" then to be put back into proper position. I got my suspicions confirmed by the user of that TT unit, saying that there was a strong possibility of having a history of the unit being dropped and also that the unit originally operated at proper sound volume that at some point has dramatically diminished.

Thanks to you 'fhantazm' it was a seamless job and writing just this post took me a LOT longer than fixing the TT One but I wanted to show my gratitude to you and hopefully encourage others to explore the possibility of fixing their TTs. The job is simple enough but someone trying to undertake it MUST have some previous experience of doing a similar disassembly and putting the unit back without damaging delicate parts inside and the speaker grill itself, to be on the safe side. Without this confidence I would STRONGLY suggest to delegate this job to an electronic engineer or friend with similar understanding of the delicate nature of electronic/mechanical components inside such a fine unit as TT certainly is.
