Background:

I've called TomTom support, and they don't support Linux.

I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work.

However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering.

However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4.

I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way.

Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine.

I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure.

My Question:

I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on?

Update: apparently dund is a legacy tool that's going away. What replaces it?
