Re: tomtom go 300

Its likely to have blown IC's 24 , 25 and also sometimes possibly 26. You might also have blown the reverse polarity protection diode. Tomtoms damaged this way require a specialist repairer as the solder joint are much too small for the average electronics guy to solder. If you have no knowledge of this type of soldering or if you have not got the special soldering equipment then it will have to go to someone who has repaired these before or go back to TomTom for repair.

Wil not turn on

Put the receiver in the charging cradle. Does the green charging light appear? If it does not, you might just have a defective cradle and hence a completely flat battery; try charging with the car charger and retry. If it doesn't charge with either charger, the power section of the TomTom is obviously gone.

Assuming you now have a charged TomTom, keep the power button pressed for five seconds. If it does not turn on, try resetting it by inserting a paper clip in the RESET hole hidden below the front cover.

If it still does not turn on, it's either a defective power button or a faulty mainboard, and I'm afraid you can't easily fix either; you'll have to send it to maintenance.

Let me know how it goes...

I have a tomtom one 3rd edition, charged it up for 4 hours and it doent work tried reset and it still dont work

TT one's are famous for the car adapter going bad and supplying more than the required 5 volts to charge the tt. Unfortunatly the result is a burned componet on the board. If it is less than a year old here in the states and you you have your receipt contact TomTom for a replacement. If you don't have a receipt then you have a paper weight. It still has some monatary value, sell it on ebay and people will bid on it for the parts.

I have had my tomtom one XL for almost one year. The car adapter (charger) cord went bad and they were backordered on the tomtom website so I purchased a radio shack universal adapter for navigational...

More than likely the generic charger sent more than 5 volts to your tt and burned a few rectifiers. You could try and tell tt the original charger did this but if they say no you are out of luck. You could put it on ebay and get something for it.

TomTom 510 Sat Nav

Most likey its not worth fixing. Look at it like this. While it may have only been 6 volts versus 5. One volt in a 5 volt system is a 20 percent increase.
If you took something that ran on 120 volts and plugged it into a 144 volt source you can figure the damage that would do.

Tom tom not working

  1. First , try a re-set through the 'reset' hole underneath the tomtom. 1 quick short press is all thats required. Unlike others suggest , you do not need to hold it in for anything longer than half a second. You should feel the switch 'click' as its a tactile switch. Don't press too hard as you can damage the switch and cause it to lock ON. Once pressed , try turning the tomtom on as normal. Sometimes a tomtom battery can drop below its normal "shelf" voltage ( normal is about 3.8 volts ). A tomtom charger has a protection circuit inside to stop or slow the current it gives out if there is a short. If your battery HAS dropped volts TOO MUCH ( less than 3 volts ) the charger can "see" the tomtom battery as a "short" and the charger therefore shuts down and doesnt charge the battery. You could leave the charger connected and HOPE that the very small amount of current it's putting out will eventualy bring the battery up over 3 volts. Once it is up near its "shelf" voltage ( called shelf voltage as that is the voltage the battery is at 'on the shelf' ie . when its not powering anything ) the charger will begin to charge as normal....... OR ... you can gain access to the battery and charge it from a bench power supply that has voltage and current meters. Once again , once the battery voltage gets something near 3.8 volts the normal tomtom charger can be used to charge it. You caould connect another normal battery to the tomtom battery just for a few seconds ( not recommended and can be a bit dangerous ) if the normal battery is such as a PP3 9v type it should bring up the tomtom battery to over 3.8 volts in a few seconds. The tomtom can then be charged as normal. .............. It is also possible that some internal IC's ( chips ) have blown inside the tomtom and unfortunatly this would require a specialist repair centre to replace them as they are really very very small and are not a normal soldering job. Good luck. ... if this post has helped you or interested you please rate the author.
