I have the unit sat in front of me,

I have already hacked access to the gsm modem part and have that fully functional, just trying to chase down the gps side now.

the unit breaks down into 3 parts (if you ignore the antenna)

part one, motherboard, contains custom cpu, flash rom and a low frequency transceiver

part two, interface board, contains power regulation for the gsm / gps module

part three, gps/gsm module, Falcom a2d-si-900-1800 module, Nice unit this one, contains full gps and gsm modem in one small unit.

currently I am ignoring the motherboard as that starts applying custom settings to the modem, (setting message centre settings, gprs settings etc) I have the interface board hooked up to 12v and have got the gsm modem working to the point where I can use it to connect to the internet and have it auto answer incoming calls

Jess--:
cracked the system, now have a board I can dial into via a modem, the board auto answers the call and starts sending back raw NMEA (gps data format) messages.

one real time vehicle tracking system  ;D

Don't know if you have any notes on what you did with the minorplanet unit, but do you think you could explain how you got it working as you did?

Got two of these sitting on the spares shelf and thought I might be able to reuse them before I break them down.

I appreciate it was 6 years ago..................

Thanks
