Anyone using his Blackberry Bold 9700 for turn by turn navigation / gps in a Mazda 3?

If so, some very basic questions I have:

- what mount do you use / recommend (make and model please) - there are many in the market but I can't find references of people recommending any specific model for mazda 3. Looking into something that doesn't require drilling nor adhesives, and that can be installed in the dash. Hopefully discrete enough not to attract thieves, or easily removable.

- what turn-by-turn navigation software do you use / recommend (navtel, garmin, googlemaps, blackberry's own)

- could you get the turn-by-turn navigation software to speak through the car audio system over bluetooth?

- what blackberry charger you use (make / model)

Thanks
