BMW CCC failure may cause navigation to keep rebooting.
In most cases, the CCC needs to be replaced or repaired.
Try this as a temporary solution. May not work in all cases.
- Get inside the car
- Turn on ignition to position II. All dash lights turn on.
- Allow at least 5 seconds for the Navigation to get all the juice from the battery.
- Now start the car and hope that the navigation turns on. It may take a couple of restarts but it normally starts.
When you start the car as soon as you turn the ignition on, there is a huge current draw from the battery that goes to the starter.
This draw put the CCC in a rebooting loop. By allowing the CCC to power up first you have a better chance of getting it to turn on.
CCC Permanent Fix
To fix the Navigation problem at the dealer you will spend anywhere between $1000 and $1600 in average.
A cheaper fix would be to use companies that specialize on BMW CCC Repair. Send them your CCC, they will fix it and send it back.
