How to Unlock TomTom GPS
I have used several different GPS manufacturers' GPS devices, personally I like TomTom better than Garmin and I believe TomTom 702 GPS device has the best price and function ratio, also it is very easy to upgrade to TomTom 940 by yourself which will save you about $300.
Below I will describe how to unlock TomTom 702 GPS. In essence, all it requires is a new license file (.dct) generated based on your device ID and the MAP info. Please note this example is based on Mio C320，it should be similar on other devices.
