So I did a little more digging in to this and after speaking with a rep a Garmin (working at Tiger Direct lets me speak to more knowledgeble people then customer service
) "apparently" this should work WITHOUT a data plan. The software is installed on the BB, and you use Garmin's service to get the maps live via bluetooth. This is taken directly from the add,
"With Garmin Mobile for BlackBerry, youxxx8217;ll have access to FREE
wireless data services. This dynamic content allows you to route around traffic tie-ups, view the local weather and find the least expensive gasoline prices"
I'm gona confirm all this next week with the rep who's looking in to it and if that is the case, wild! No need for an expensive BB data plan to have GPS
I'll let you guys know
