X5 LAT-LONG NOT UPDATING

Dear all,

I have an X5 modem that does ABS but it GPS does not update according, there by causing  the system not to be on the network. The Modem is connected to a seatel Dac 2202. The Dac updates it GPs from a TMS connected to it. and the modem console port is also connected to the the TMS console port through a straight through Rj 45 Cable. Any one with any possible solution on this should pls help.

Reghards,
