Thanks beej,
Why not the 3300 ? (now the 3400 with voice I think)....
The GPS is line of site, and with the mini's steep windscreen, I wasnt sure that I would get a good fix if the Ipaq was in the car (with the GPS expansion jacket) rather than stuck to the windscreen with the supplied mount kit. If I did fix it to the windscreen, then I would have the trailing wires to the power source down the dashboard. Basically I can get a fix without worrying about the position of the IPAQ.
This allows me to put the GPS unti in the optimal position (at the base of the windscreen as far forward as possible), but keep the Ipaq unit in the car (and relatively unaffected by glare).
Saying that, I was tempted by the 3400, but I'm a gadget freak, and love to try new concepts, also as the Compaq is Bluetooth enabled, it seemed to make sense.
YES

the IPAQ talks directions, in either a female or a male voice (havent tried the male voice yet!).
Final note, the product guide said that it might not work with 'heated windscreens', and might need an external aerial... I was sweating with that as our Mini it, but it seems to work fine.
Cant think of any negatives at the moment..... the GPS unit needs AAA batteries, but I just put rechargeable Nimh's in, and 'should' get 30 hours from each charge.
Cheers.
