I've got this up and running on my Samsung Omnia which uses Windows Mobile 6.5. Should work for any Windows Mobile phone. The files include step by step instructions for the most computer illiterate people. Works like a charm... Nothing else to say!

Product Information:
With spoken turn-by-turn directions and millions of points of interest (POIs), Garmin Mobile XT puts robust content right at your fingertips. You can upload custom points of interest and conveniently navigate to contacts in your address book. Garmin Mobile XT also provides dynamic data to help you make better-informed decisions at a moment’s notice. And with an intuitive user interface, moving maps and off-route recalculation, you’ll be able to navigate with confidence. It’s powerful functionality that you’ll only find with Garmin Mobile XT.
Go Anywhere

With no network coverage required, Garmin Mobile XT works anywhere. Simply plug the microSD card (with miniSD and standard SD card converters) into your compatible phone with built-in GPS and go. Since Garmin Mobile XT works outside your phone's coverage area, you'll get directions when you need them most.
Enjoy Dynamic Content*
