TomTom One 310 LCD and Touchscreen Replacement

简介

This was given to me by a coworker for repair. It is a well used GPS that fell out of a Jeep and cracked the digitizer. The digitizer and LCD are available as separate units. I opted to replace the complete assembly since there was only a minor difference in money.

Here is the TomTom with a clearly visible damage. The LCD did work, but for obvious reasons the digitizer did not.
Use a plastic opening tool and insert it between the outside of the bezel and the plastic case. It will need some effort, but the plastic of the case does have enough give to make it possible.
Continue to work the tool around the bezel. There are multiple plastic tabs that need to be released
