Cheapest GPS ever

I found the Nokia Navigator one of the cheapest deal to own a GPS. The built in Map application Nokia maps is quite ok for local use, but in Malaysia, most of the roads details are quite sparse. Here comes Garmin Mobile XT to the rescue. The common knowledge was that to use Garmin Mobile XT, you will need the Garmin 10x. Not quite. While it is not documented to be able to support Nokia 6110 (and N95), it is possible to enable Garmin MXT to use the in built Nokia GPS chip.

I have been asked many times how to do it. Here it is, the instructs.
