    Navigation Unit and Radio do not consistently startup

    Nav unit start up intermittently. There's no rhyme or reason when it will work. I've unlocked dash to view battery voltage and saw it had 11.8v, so purchased a new battery. Now reads 12.7 at rest, however, system still does not work all the time.

    I drove it 30 minutes ago to put fuel in car and it worked. Wife took it out 5 mins ago and called saying it's not working. My internet searches are not yielding anything. Has anyone had this problem before?

    50% repaired. Turned out to be the CIC headunit (radio). Obtained a used unit and works, but Bluetooth and Navigation aren’t activated.

    Do I need to code new unit to my vehicle?

    What would I buy to code it myself?

    Thanks...Brently
