3) Now, be careful here. The built-in GPS receiver in the HTC diamonddoes not transit signals in Garmin format to the Garmin XT software.So, you have 2 choices. Either go get an external Garmin 10x receiver( http://www.garmin.com ) or go buy a Garmin mSD card and slot it intoyour HTC's memory slot. This mSD card does the conversionautomatically from non-Garmin signals (as received by your built-inGPS receiver) to Garmin signals that the Garmin mobile XT softwarewill recognise.

Is it true? If it is, den wat other gps software can b used in htc diamond?
