''There are a lot of videos and web pages out there that show TomTom ONE owners how to do this. Just make sure that the TomTom ONE model you have is the same as the one in the video, for example, one video is based on a ONE XL, and the ONE 130 (30 series) circuit boards are the same...I believe. But if you have a different model, make sure you research it thoroughly before tackling any of this...and the pin connections are smaller than the size of the head of a pin, so you're going to need a lot of lighting and a magnifying glass on a stand, plus a very small pencil soldering iron...if you use a 100W soldering gun, you're going to burn up the board and get tons of solder all over everything, thus you unit is now trashed. Good Luck!''
