Condition
• When the vehicle is started, the GPS location or vehicle
direction indicated on the MMI navigation map does not match
the vehicle’s actual location or direction of travel for a long
period of time (often as long as 10 minutes):
• The issue occurs in open sky, with no large buildings
obstructing the sky view.
• The issue is intermittent, but it can occur for long periods
of time during a single day.
• The issue typically happens on very warm days when the
HVAC system blower is at a medium to high setting (auto
or manual), with air being directed out of the panel vents.
Figure 1. No satellite reception.
• When the issue occurs, the GPS navigation system
satellite reception shows 0 satellites. Due to the
infrequency of the issue, this might not be verifiable. (To
view the number of satellites being received, go to Nav >>
Route >> Select Current Position (first item in list) and
scroll up (Figure 1)).

Technical Service Bulletin
• No DTCs related to the GPS antenna or MMI system are
present.
Tip: If the sky view is blocked because the vehicle is in a parking structure, below ground, or next to large
buildings, it is normal for the GPS location or vehicle direction indicated on the MMI navigation map to not match
the vehicle’s actual location or direction of travel. The blocked sky view prevents the vehicle from receiving
satellites, and the system may be temporarily lost until four satellites can be received. This is a normal condition,
and is not related to the condition described above. Replacing the MMI main unit will not change this behavior.
Technical Background
A potential failure in the internal hardware of the MMI main unit can cause the GPS signal to be blocked, even if
good reception is available. The failure can happen at start-up or while the vehicle is being driven. The issue
typically starts when the vehicle is driven on curvy or circular roads, driven in circles (such as when driven around
a parking lot), or driven on or off an expressway.
Production Solution
New hardware and MMI software was introduced in production starting with calendar week 45 of 2014.
Service
For model year 2013 - 2014 vehicles:
1. Update the MMI software using ZUG K0814 (see TSB 2030465: 91 MMI 3G+ Various technical Issues (K0814
ZUG update; supersedes K0715 update)).
Tip: This update ensures that the MMI control panel (E380) will be able to communicate with the new MMI
main unit (J794). If the update is not performed, the MMI control panel button LED lights will flash constantly to
indicate a software incompatibility in the MMI main unit.
2. Perform the required SVM feedback according to the instructions in TSB 2030465. The required SVM code is
included in the ZUG K0814 update medium.
3. Replace the MMI main unit (infotainment control unit 1), J794 (address word 5F).
4. Update the MMI software using ZUG K0814 (see TSB 2030465: 91 MMI 3G+ Various technical Issues (K0814
ZUG update; supersedes K0715 update)).
5. Perform the required SVM feedback according to the instructions in TSB 2030465. The required SVM code is
included in the ZUG K0814 update medium.
If the SVM communication fails, leaving the DTC for “Checking Software Version Management” in the 5F fault
memory, contact the Technical Assistance Center (TAC).

included in the ZUG K0814 update medium.
4. Using Guided Fault Finding, perform the replacement test plan for the MMI main unit (infotainment control unit
1), J794 (address word 5F).
If the SVM communication fails, leaving the DTC for “Checking Software Version Management” in the 5F fault
memory, contact the Technical Assistance Center (TAC).
