Gps malfunction when I turn on gps it says no pos

You will have to buy a new GPS unit and GPS units can't be replaired.

Park shift interlock. A safety device that will only allow the key to be removed when vehicle is in park. It is malfunctioning could be as simple as a cable sticking

First do you mean it wonk crank when you turn the key have you check the security on the truck if it's the security the truck won't crank you can bypass that try cranking it with a wire from the pos of your battery if it cranks Eather a bad switch or the chip on your security system good luck

Batteries do not fuction well in cold weather. Use a better battery like the lithum or warm up the battery by rubbing back and forth on your pants both sides pos and neg.

Hello..
Code 21: Is an oxygen sensor Code 54: Is a crank positioning sensor.
Hope this helps!

Hi
If unit is as per pic I assume it has external antennae. Ensure the multi pin plug is secure in the rear of the unit and also use a fully charged 12 volt battery, Has it been working before?? Usually a rear plug problem. How old is unit. Just had a another thought, check that the polarity is correct, ie pos wire to RED (Pos) on battery. Very polarity sensitive.

Cheers cbacer

To get 36 volts, number batteries 1 thru 3. connect pos 2 to neg 1, connect pos 3 to neg 2, connect pos 1 to trolling motor controller and neg 3 to ground on trolling motor.
This is only a solution for 3 battery system.
For 4 battery system, connect 4 to 3 pos to pos and neg to neg.

Same Problem. I fixed mine with a baseball bat, hammer, and a cold beer. Lesson learned: NEVER BUY DELPHI AGAIN. NEVER..... Tell your friends. Delphi = POS

Have you gone through the "Initialize" process again? If the memory has been cleared you will need to re-initialize. Refer to page 4 of your manual. Power On > Select Language > "ENTER" > INITIALIZE screen > "ENTER" > Select Region > "ENTER" > Select Area > "ENTER" > Enter Elevation > "ENTER" (if you don't know elevation, press enter) > Enter Time > "ENTER" > Enter Date > "ENTER"
