UNAVI Technical Guide Checklist

When technical support inquiry is received regarding the system freezing or locking up, follow the guideline below and record problem with detailed information as possible:

Example 1 – Froze while navigation was loading; problem appeared after 3 wks; occurs within 2 hours; vehicle is driven mostly in Orange, CA (or Orange County) area; advised customer to update system with the latest firmware; proceed with RA if problem persists

 Example 2 – Froze while booting; problem appeared after a week; recover OS using NK.bin and update with the latest firmware; proceed with RA if problem persists

Procedural Checklist

1. Check firmware version (Main Menu: Settings > Program > under version information)

2. When does the symptom occur? (Navigation, playing MP3, listening to radio, during boot-up)

3. When did you first notice the freezing issue? (after 1 day, week, month, etc.)

4. Duration of symptom (every 30 minutes, 2 hours, random, etc.)

5. Occurrence of symptom (once a day, twice a week, 3-5 times a month, etc.)

6. If during navigation, does it occur in the same region? (Determine approximate location)

NOTES

• If firmware is not up to date, update system with the latest version.  If problem persists, request for RMA (MUST replace and return all components).


• If firmware version cannot be confirmed (in cases where system won’t load during boot-up), request for RMA immediately (MUST replace and return all components).


• If system successfully boots up via SD Card using the NK.bin file, update system with the latest version. If problem persists, request for RMA (MUST replace and return all components).


• Use GROUND wire located on the SMART cable to ground it to the vehicle chassis frame.


• Inspect for any peeled off cable sheath and/or damaged outer insulation; wrap it around using an electrical tape as necessary.
