BMW Navigation system may fail due to a defective Car Communication Computer, known as CCC. If BMW CCC fails, BMW navigation and iDrive will not work.

In some cases, the navigation system may work intermittently. The cost to repair or replace the CCC navigation unit at BMW dealerships varies between $1000 and $1600.

Another popular solution for BMW owners is to use a third-party vendor who offers BMW CCC Repair and will repair your existing unit. CIC can also fail.

CIC is the newer system and more powerful than CCC.

BMW CCC PROBLEM CHIPUnfortunately, many BMW CCC units fail after five years of use. Some common BMW CCC failure is due to a processor chip partially separated from the PCB or a failed capacitor.

The owner may remove the CCC unit and try to heat the onboard chips with a heat gun. This method doesn't always guarantee that the CCC will work, and you can cause more damage with this method.

Before you spend hundreds on BMW iDrive CCC repair, there are a few things that you can try yourself.

The CCC units can fail due to poor circuit board connection or chip problems.

  • CHOST
  • ASK
  • CTUNER
  • MOST gateway

Some of the symptoms described here may not always be due to bad CCC. For example, certain CCC failures can cause no sound.

A 'no sound' issue may be caused by a bad amplifier or a damaged optical cable. In the next section, we will discuss some of the most common causes of BMW CCC failure.

Alternative Repair

One of the cheapest ways to fix BMW CCC units is to find a company that offers BMW CCC repair service. You will spend under $400 to repair your damaged CCC iDrive system vs. 1000+ at the dealer.

Remove your CCC from your BMW and ship it to the repair facility.

A technician that specializes in repairing the BMW CCC unit will test and repair your unit.

Once the CCC is repaired, it is returned to you for installation.

The advantage of this method of fixing a CCC is that it is a cheap way to fix a CCC. Plus, the unit doesn't require any programming.

If you use a repair service, your vehicle data, including stored VIN, mileage, or immobilizer code, will not get erased. Coding is not necessary.

If you use a repair service, you can ask your service provider if they can also perform the following coding if needed:

  • Change CCC language
  • Upgrade to the latest firmware
  • Upgrade navigation maps
  • Enable MP3 playback for CD and DVD
  • Enable AUX input. May require adapter
  • Install the Bluetooth module inside the CCC. This will allow you to stream music from your phone.

Failed Capacitors

Damaged BMW Idrive CCC Board

The capacitors in the navigation board (PCB) mail fail. If this happens, you may notice that the CCC is stuck on the BMW logo.

The capacitors can be visually inspected, but this requires the removal of the BMW radio.

iDrive Sofware Issue

A CCC software error can cause a complete system failure and stop the CCC from booting up.

If your BMW is still under warranty, have the dealer diagnose your CCC problem.

Ask for the CCC to be updated. This may fix CCC problems in some cases.
