As a motorbike rider im also interested in something similar but using a wired connection.

Out of the box my N95 does what my N900 cant which is extremely frustrating, especially as i haven't the time or skills to programme and im reliant on the community to develop apps.

2 things i really need for work from my N900 whilst riding my motorbike

- Auto answer
- speech navigation.

Auto answer has been available on Nokia's for years and suddenly it gets withdrawn from this model In future i will look more closely at the feature set of the phone when im considering my needs and take it as a lesson in assumptions..........

I did create a post a while back (auto answer) but i had no response.
