Maybe MB can send Microsoft 'Service pack' upgrades using the tel-aid (or whatever they call it now) system too.

Question: What impact does using a cell phone with its own antenna have as opposed to using a car mounted one like the manual says to do. Could that cause some of the computer/readout glitches? I'm trying to convince my wife (the Electrical Engineer) that it could play a part.
