The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition / Concern
Some customers may complain of no GPS on NAV radio.
Recommendations / Instructions
If this concern is encountered, determine if OnStar is able to accurately
locate the vehicle. If it can
locate the vehicle, this concern ma
y be the result of the coax cable being routed incorrectlyduring
repairs causing it to bypass the splitter and go straight from antenna to the OnStar module. If this
concern is encountered, install the EL-49903 test antenna to the Radio/HMI and evaluate the GPS
operation. If the GPS signalis restored, inspect for incorrect coax routing as described above and if
found, reroute the cable so it does not bypass thesplitter.
Warranty Information
For wiring repairs coveredunder warranty, please refer to latest version of bulletin 10-00-89-005 for
warranty information on wire/connector repairs.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is
resolved without completing every step, the remaining steps do not need to be performed.
