I've been a dedicated Tomtom convert for 5+ years, but since its not available on the storm yet, I downloaded the 7 day free trial version from Garmin: full version is £60, before 20% bb lounge discount.
Tried it once...not happy with a few things. The maps weren't detailed enough (I like to know where the rat runs are) and it had a crazy route in mind for my daily commute.
I was going to give it another go but now it has an error message at startup: "unable to authenticate" and after retry: "unable to fullfill request. please try again later. (code:99502-051)"
According to a very unsure person at Garmin the software doesn't like 3g? and it runs better on gprs?

How do I chose what connection method an application uses?
I can't believe this is the problem though.
