Google Maps for Windows Mobile was recently updated to 3.3.1 which solved a Layers issue that caused the phone to crash. Besides solving the Layers issue, it turns out that it also brought support for HTC HD2’s digital compass. Yes, that’s right now you can use the digital compass on your Google Maps app for Windows Mobile.

The location dot changes into a blue arrow when you are in the My location mode. If you don’t see that happening, you may try walking and turning around a bit to initiate the digital compass.

The digital compass works only in My Location mode. Unfortunately, it doesn’t work in combination with GPS, and you need to have GPS turned off in order for the compass functionality to work properly. With GPS turned on, the arrow always point to north. Still great news.
