SPS / GPS Network Connection Info

In order to connect to the appropriate GPS network for your project please follow the steps recommended below.

Step 1: Be sure to check your mount point and that it matches up with the network you are trying to connect to. Mount point ex: CMR_GPS, CMRP_IMAX, VRS_MSM5, CMRX, etc.

Step 2: Sometimes in order to get connected to a new network you will need to power cycle the SPS head unit. To do this hold down the power button for approximately 60 seconds. This will clear the junk files in the head unit.

Step 3: While connecting to a network be sure to rotate the GPS receiver around and move around with the unit.
