Nice Picture tlcasper. Also, those green bars are representing how many sattelites the device is reading for navigation. There are in fact other satellites your device reads, but aren't for navigation purposes.
Ok, I did some more testing last night. I SUCCESSFULLY had Google Maps going, following me down the street very accurately, and I minimized, opened up PIE, and got on the internet, switched back to Google Maps and is had still been following me the whole time, so 1st of all, you CAN use the internet and GPS at the same time. Google maps goes as far as to specifically tell you that you NEED a data plan to use this program when and if you happen to lose your data coverage. Garmin/Tomtom, on the other hand, never mentions it until you try and use the extras. GPS is 1 way reading of a signal. My phone isn't communicating (
sending any info) it is just receiving info from the satellites.

If their products work on my phone, then this is how they are working. Not from my data plan.
On the other hand:

I believe this is what you're talking about. This is where it needs the data plan to assist, but not always required. To relay the information about my position
to someone, i.e. police, it would need a data plan.
I don't believe that my navigation programs are utilizing A-GPS on my hardware. They might use it as complimentary, but not exclusively.
But no where on Garmin's site or Tomtom's site do they mention that I need a data plan to use GPS functionality. Only for the extras.
The Mogul is the same. Over at my other forum, everyone is MOGUL, and I learned from them. I know the mogul is the same. Telenav (Sprint Navigation) on the other hand is blocked unless you have that plan. They make you subscribe because they can. Proprietary software.....
