MC8704 GPS configuration error

Hi, I have a MC8704 module and I get an error when configuring the GPS.
The sequence of AT commands for configuration is:

ATI3

OK

AT!GPSTRACK=1,255,30,1000,1

It seems as if the module did not have GPS capability.
Revision module is: T2_0_2_1BAP R439 CNSZXD00000128 2011/09/19 17:26:58

Please help!

Thanks

what is the reply of AT!GPSPOSMODE?

Hi, the response of AT!GPSPOSMODE? is:
MASK: 0x00000000
OK

Is it necessary to set the bit 0?

thanks

Thank you very much,
it works properly once configured mode:

AT!GPSPOSMODE=1
