Seeing as Paul has flagged up a conflict I'd best watch my Ps and Qs.
I wonder if he works for June at Box telematics.
Anyway suffice to say that there is access available to the control
channels in gsm which enables transmission of certain data without any
handshaking protocol, it's all beyond my knowledge of how and why but
it is being done. I wonder if it does constitute an unlawful act but
doubt it. I looked into it after being trapped in a vehicle with a
broken pelvis some years back, I dropped my phone and could not reach
it. E-mail is valid if you need more but it's not my field by a long

fairy nuff but real time tracking costs the same ;-)

Leaving aside what your main reason for the gps unit is, you said it
may be an additional attraction to offer route planning. I have been
in posh cars with sat nav and apart from the annoyance of the voice
prompts the only thing they offer over my personal navigation software
is re routing if the road ahead is blocked.
With these little hand held things offering auto routing it looks like
all the functionality but re routing is now in the hand held unit.
In fact I seldom connect the garmin 12xl into the laptop and normally
plot a route on my desktop, upload it to the garmin as waypoints at
major intersections, becoming more frequent as I near my destination.
It is quite interesting how close the actual roads/track are to the
plotted course and how near to a straight line a journey usually is.
My last trip to Gt Yarmouth was upset by the M11 being closed at
stansted, I did need to look at a map but a diversion up the A120 soon
had me back on track, until I met a 5 car pile up just south of
norwich :-(. I was only 20mins late overall though.
