Situation:
1. ..... From this forum, the manual as well as trail & error, I "know" the "built-in" connectivity and the "owner sim" (original AT&T) connections use different hardware/software and serve different purposes
2. ..... I have also read all (?) references here on updates, particularly as they pertain to the 3G situation, such as the Topics Field Action K444NAS1: Telematics Unit.
3. ..... This update is scheduled for next month (we are a long way out and there is little traffic here, so some of the "extra" features are not urgent)
4. ..... Since it hasn't been that urgent, we have also NOT renewed the "elapsed" AT&T data plan; so we still have an AT&T account, it shows no data plan (but the facility to renew it) and the "owner sim" is still sitting in its slot under the arm-rest
5. .... Driving along, the connectivity icon (top right) routinely shows one of three states: 3G, or trying to connect (moving dots), or a crossed-out "C", showing no connectivity; Note: even though there is no data plan, we still get the 3G showing when in an AT&T coverage area
6. .... Invoking the search function in Navigation, when there is no connectivity or when it is trying to connect, brings up a message that warns that there is no internet connection, that the results will be limited to the data on the downloaded maps and that results would be better if the car were connected. Makes sense to me.
HOWEVER
7. .... When the screen shows 3G (remember there is NO data plan), I can search for petrol stations restaurants, etc., etc. to my heart's content, and they duly appear
8. .... Similarly, with 3G showing, I can bring up the traffic view (which in may case nearly always says there is no traffic)
What I don't get:
9. .... even with 3G showing, the "Live" apps (weather, news, flight tracker) tell me that they can not make a connection or update
SO
What (else) am I really missing, if I don't use the connection that comes with the "owner sim" and corresponding data plan?
