In my 2001 Buick Park Avenue the GPS and Analog cell phone are in the 
trunk behind the passenger side seat.

I removed the unit and the GPS board looks like a Motorola Oncore 
VP/UT+/GT and there also was an antenna that looks like a, "Motorola 
Antenna 97 GPS antenna", Motorola part number is GCNAC1232A.

With GM's analog OnStar no longer supported, this may be a low cost auto 
salvage item.

Can some one confirm that GM used a board with the same pin outs of the 
  Motorola Oncore VP/UT+/GT. With no previous GPS board experience, I do 
not want to damage this board by being wrong on the power connections.
