Interesting point, but AGPS is working even inside buildings....
the chip will make about 200.000 calculations parallel and so the
AGPS (assisted GPS) will be able to work even with low signal.
I can imagine that there is still enough signal in such cars.

And no. AFAIK it will have no atenna connector - and I think there
will be no need for it.

Should be added on the V2 whishlist ;) 
Is there already one?

Adding ideas are important to 
- show how powerfull such an smartphone with an GNU/Linux SDK and AGPS
  will be
- and to avoid that companies block innovation by ask for patents for
  ideas - publishing ideas on this list will be a priory against such
  patents :)

So go on to write about your ideas and wishes :)

Real GPS Outage - I would like to see a falling back system
based on GSM cell info, but maybe also some day with digital radio
mondial and accurate time broadcasts so that the device could calculate
the position with the help of mw/ukw radio stations.
