Navigation (GPS/SD Card)
- 1. System features/Misdiagnose cases
Inspection Description (1) System features - Displays map using GPS/DR system, calculating GPS signal and vehicle speed
- Possible reception issue in poor reception area
- Additional wait time required after battery re-connection
(2) Misdiagnose cases - Black Box related: GPS reception issue from black box noise
- Cluster speed and navigation speed: It may vary (Design spec)
- Set Navigation display "North" will lock display of direction
- No SXM reception due to environmental issue: Buildings, Tower turn-table parking lot
- Displays map using GPS/DR system, calculating GPS signal and vehicle speed
- No GPS Reception/Inaccurate current location
Issue Inspection Description Reception/Inaccurate current location (1) Duplicate issue - Duplicate using AVN
- GPS reception on Engineering Mode

- 3-1. Enter Engineering Mode
- Menu > Settings > System Info > Storage or SW Info > Touch left bottom 5 times, right bottom 1 time
- 3-2. DR information at Engineering mode (Normal: 3 or more STATUS 1, SNR 40 or above)
- 3-1. Enter Engineering Mode
- Antenna connection at Engineering mode
- Engineering mode → Care → Vehicle I/F diagnose → GPS ANT SHORT/OPEN (Normal: NOT SHORT, NOT OPEN)
- If connection is "Open", check cable connection
- AVN connector
- Antenna connection
- Cable connection
- Move to good reception area and re-test (Poor reception area)
→ Proceed with below step if this issue continues
- GPS reception/Incorrect current location
Issue Inspection Description No GPS reception/Inaccurate current location (1) Duplicate issue - Duplicate using AVN
- GPS reception on Engineering Mode

- Duplicate issue
- Compass icon is activated (Normal: Red compass color)
- Check if map displays current location
- GPS activated (Normal: 3 or more yellow "Receive" icon)
- Check DR at Engineering mode
- Engineering mode > Module info > Navi engineering mode (Normal: 3 or more STATUS 1, SNR 40 or above)
- Move to good reception area and re-test (Poor reception area)
→ Proceed with below step if issue continuesNo GPS reception/Inaccurate current location (2) External/Environmental issue - Black box
- Cable connection
- Black box related issue
- Remove power on black box and reconnect
(Many cases with GPS reception issue due to black box power)
Courtesy of KIA MOTORS AMERICA, INC.
- Remove power on black box and reconnect
- Antenna connection status on Engineering mode (Antenna ↔ AVN connection cable)
- Remove power on black box and reconnect (Many cases with GPS reception issue due to black box power)
- Engineering mode → Care → I/F → GPS ANT SHORT/OPEN (Normal: NOT SHORT, NOT OPEN)
- No GPS Reception/Inaccurate current location
Issue Inspection Description No GPS reception/Inaccurate current location (1) Duplicate issue - Duplicate using AVN
- GPS reception on Engineering Mode
- Compass is activated (Normal: Display 3 or more)
- Check DR at Engineering mode (Normal: 3 or more STATUS 1, SNR 40 or above)
- Check current location
→ If reception is good, proceed with drive test to duplicate issue- Move to good reception area and re-test (Poor reception area)
→ Proceed with below step if issue continues(2) External/Environmental issue - Black box
- Cable connection
- Black box
- Remove power on black box and reconnect (Many cases with GPS reception issue due to black box power)
- Antenna/Antenna ↔ AVN Cable connection status
- Check antenna connection
(1) Check rear AVN antenna connection status (Blue color)
(2) Joint antenna connection status
→ Check vehicle diagram, 'A pillar', 'C pillar'
(3) Check antenna connection at roof
(4) Cable modification
- Check antenna connection or Engineering mode
(1) Engineering mode → Care → l/F → GPS ANT SHORT/OPEN (Normal: NOT SHORT, NOT OPEN)
No GPS reception/Inaccurate current location (3) Defect caused by Ext. parts
(4) Related TSB
(5) H/U defect- If no antenna connection, replace antenna and re-test
- Use test antenna or use from dealer/MRC inventory
- Check related TSB, apply latest H/W and S/W (Example: TSB for YG AVN 4.0, Add FELT to FFC Cable (Improve CD and power problem))
- If antenna connection is good, replace H/U and re-test
1) Additional wait time is required after disconnecting Battery
- If antenna connection is good, replace H/U and re-test
Others - For additional analysis, store log information
[Setting - logging ON]
- Menu → Settings → System info → Storage → press left bottom 5, right bottom1 → module info(3/3) → Navi Engineering mode → Input 120421 → GPS/DR → GPS Logging ON → Drive TEST → GPS log export (USB memory connection)
- If issues duplicates during drive test, request SW analysis (GPS Module Vendor)
- SD Card recognition fail/Error message
Issue Inspection Description SD Card Recognition/Error message (1) Duplicate issue - SD Card recognition
- Error message
- SD card recognition (Normal: recognize, reboot)
- Error message (Map recognition fail)
- Genuine SD Card use (Check compatibility with H/U)
- If SD Card fails to recognize and displays error message,
- Proceed with below step for further analysis
(2) Visual inspection - Damaged SD Card pin, foreign object
- Damaged SD Card socket, foreign object, bent
- Check for damaged PIN SD Card must be unlocked
- Damaged SD Card socket, foreign object, bent
(3) SD card files - Check data in SD card using PC
(Check model, compare data volume → unnecessary files, data for other model)
- (2), (3) If issues still occur, replace H/U and re-test
