How to Replace the Battery in a Tom Tom 510 Sat Nav
What Screwdriver do you need to undo screws on a TomTom 510 SatNav?
If your TomTom has stopped working and doesn't hold any charge the chances are that the battery has failed and needs replacement. Our TomTom 510 wouldn't turn on anymore but had previously not lasted very long without being connected to mains power so I thought the battery might be a cause. Checking online it seems that the battery in a Tomtom can last for around 2 years so the 6 years we got from ours was good going!
The price of the TomTom battery on Ebay was £8 and the screwdriver head was £2.50 so for a total outlay of £10.50 we now have a working SatNav and have saved the £100+ cost of a new one!
This guide is an excellent and detailed instruction on how to replace the battery in a TomTom 510 satnav but also should cover other TomTom devices like the 520,710,720 etc.
The only items that I found missing from the guide were to explain that you needed to remove the SD card before starting (found out the hard way!) and which screwdriver you need to undo the screws to open the TomTom up.
Consulting my local hardware store, the excellent Johnsons of Rainham, I was able to determine that the screws needed a T-6 Torx screwdriver to remove them. The cost of this was £2.50 but compared to the hassle the writer of the TomTom battery replacement guide above had it was a doddle to remove the screws and no problem at all to replace them without any of the injuries to the hands that they received.
There are 12 different screws including the 4 on the outside case so it is well worth investing in a proper tool to open them rather than modifying a philips or flat head screwdriver.
