I have a 2002 Isuzu Axiom. The clock and the compass will not set. I read in the owner's manual and supposedly the clock and compass are supposed to be set by satellite. The manual stated that if for any reason the clock/compass should be incorrect you need to disconnect the negative battery cable for 3 to 5minutes and then reconnect. The car should then read the new satellite signal and correct the issue. I have done this and now 3 days later I still have no compass or clock. Any ideas on what to do for this?

TAKE IT TO YOUR DEALER,GPS SENSOR MAYBE BAD WHY ITS NOT PICKING UP THE SATELLITE READING.
