Re: Possible to use Internal GPS in no coverage area?
I'll add my 2 cents to this.
I have used my Touch Pro in Europe (both Belgium and Germany, using several different apps, but mainly TomTom for actual road use) on two different trips. Obviously I didn't have cell signal while there! But I did notice a few things that might help people.
1. I updated the "QuickGPS app that comes with the phone just before leaving. It comes with the TP stock, and is supposed to speed locks by having the most recent sat position data on the phone (rather than the GPS having to aquire the data from the sats directly once it finds one). The data is good for about a week which will cover most folks, plus you can update it if you can get a wi-fi connection.
2. (most important IMHO) Try to get an initial lock WHILE NOT MOVING. I found that the GPS seems to lock much much faster if I take a minute to get an initial lock.
3. If you're having issues, try an app like GPSViewer or BeelineGPS to monitor the lock progress. Get a lock there, then launch your preferred app. It's not necessary, but can alleviate some of the stress. Note that GPSViewer won't show that final lock from the "GPS Status" screen. Seems like a glitch, but if you saw it get 4-5 sats, then shift to the setup tab, then back to the GPS Status tab and you'll see the final lock.
All in all it does pretty well. The big challenge is the initial lock (cold start). I think the driver is probably optimized to assume a USA location, so if you're in a area with poor sky visability (e.g. buildings, mountains, lots of trees, remember, the phone has an antenna to receive VERY weak signals from sats) you will take a lot longer to lock.
Hope that helps someone get this working.
