I, as initiator of this discussion, first have to apologize for my 
assumption that latest SHR still cannot handle GPS. It can, I now made the 
same observations as Sylvian did: GPS receiver quality is poorer, TTFF is 
slower, but it works.

I have two FreeRunners (one for testing new releases) and that one had the 
GPS cable broken. I think it was from the many times 'shaking out that 
I managed to re-solder it somehow but with only little success:
I only get the GPS time, but no fix, and it seems to mee that this also 
only works on the January (or comparable) release of SHR, not for actual 
(July) ones.

Finally I'm glad to have navit working again, since I'm about to go to a 
business trip from Germany to US, having a rental car there with probably 
no navigation on board ;)
