Can someone help me with a project? I have a 2002 TrailBlazer LTZ with the obsolete analog OnStar system. I have the unit sitting on my desk, but can't identify which model of the Motorola(?) GPS is in this vehicle. I've done internet searches on part numbers, but nothing comes up.
Can someone help me identify which unit this is, and help me find a way to access the GPS data? I will tie the data feed into a computer and/or a ham radio APRS system.
The various numbers on this unit are listed here:
OnStar + GPS package:
Part NO: 12451224
Model NO: OSF1S14D10
STID (20S): 0002087304
TRACE (T): BV1224T211550814
FCC ID: IHDT5SZI EES
CANADA: 109 182 197A
ESN (22S): A84CBA6BBJT
Internal unit, sealed in metal shielding beneath main board with connectors.
(Is it GPS or the cellphone radio?)
FCC ID: IHDT5ZY1 EE3
CANADA: 109 182 332A; TYPE ZYKA
