I have been trying Garmin. Pretty good. However IMO no Blackberry solution is as good as a decent dedicated device. Adequate/Good Enough - Yes.

My experience is the GPS processing isn't quite as good on BB apps [in comparison to a dedicated device]

For example Garmin [on the BB] calculates my vehicle speed. It is close [+/-2 mph], but it doesn't update as often as my Navigon. My dedicated Nav device (NAVIGON) is dead nuts accurate.

It takes a little longer to recognize that I am deviating from recommended route and start a route re-calculate. In addition, that re-calculation takes a little longer.

On the plus side the Garmin software is integrated with the phone and you can look things up like weather, up to date restaraunt listings, etc.

On the negative side:
- No signal for the phone, no navigation. Mothership is required
- Phone calls interrupt the nav and you might miss a turn
- I suspect just receiving e-mails also hinders processing behind the scenes, but no proof

Overall I liked the Garmin app. It would make an excellent business travel companion. [but I still plan on bringing my Navigon with me]
