The GPS device runs off the battery ... so, you need to charge the battery (fully, or enough to power the GPS) before you start using it again. For clarity, if the battery is not charged, the GPS will not run when plugged into a power source.

You'll want to (first) backup your navigation software and map data(base) onto your PC (using HOME or Windows Copy). Then, remove some of the "not used" data from the GPS ... e.g. voices, symbols (e.g. cars), etc. After that, you may wish to do a DeFragmentation on your GPS storage device ... using the usual Windows (defrag) utility ... e.g. from File-Properties-Tools-Defrag.
Then try connecting the GPS (using HOME) to your PC again, and see if there's enough space for updates.

It appears that your screen calibration is "off". You'll want to get it re-calibrated. Or try it yourself ... using a cal.txt file to over ride the original calibration data burned (in factory) in its Flash memory...

It may be possible that the (Europe) map version that you have doesn't have voice instructions (data) that is compatible with the navigation software (that you have on the TomTom GO 500). If you can indicate the navigation software version and the Europe map version, that possibility can be checked further.

Leave it plugged for 3 to 4 hours. You can check the charging at half time.

Replace the mount with a new one if cleaning the rubber suction cup fails.
Use a 'alcohol wipe'

  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.

Sometimes these screens can just die, offering the "opportunity" to buy a newer technology! First thing to do is a full reset - check the manual to find out how, but it's going to be something like a little button, maybe inside the battery compartment, look for a small hole that might take a paper clip. Failing that, take it back to the store, especially if it's relatively new.
