Hello,

After map update (2022-2 Europe East) iDrive restarts every 20 seconds.
Car is equipped from factory with Entrynav (F25 2017), updated to latest I-step (21-03-545) and was working fine after map 2022-1 Europe East update, done 3 moths ago.

After connection of maps 2022-2 (on USB that was working previously), HU restarted few times but eventually initiated update. Once completed, it restarted again and it is in this state a third day in a row. It boots to main menu, that I can browse it for 20 seconds, but then is shuts down and restarts.

Actions performed so far:
  • attempt to update to previous maps - not possible as HU restarts after confirmation of update
  • re-programming to the same software using Esys - no difference
  • disconnected battery for 24 hrs - no difference
  • delete map data using Tool32: entrynav.prg: ARG;NAVI_MAP;STR;0x01 - JOB_STATUS=OKAY but maps are still present as I can enter to Navigation and see car position on map for 2 sec, before it restarts.
  • downgrade to I-step 18-03-520 (different (older) SWFLs) using Esys - no difference
  • update again to I-step 21-03-545 using ISTA+ - no difference. Right after completion, Navigation was greyed out, but HU rebooted regardless. Now Navigation is available and reboots.

What else I can do ?

When you run Check FSC Status with E-Sys, what does it show for ENTRYNAV?

Do you have any relevant error codes?
No error codes in ISTA+.

Since car runs normally, I took it for a spin (1 hr total) and after 10 min of driving, HU restarts stopped and behaved correctly, including fully functioning navigation, until I turn off vehicle 20 min later. When I turned it on again, for next 30 min, it continued rebooting and still does now. In summary: 10 min not OK - 20 min OK - 30 min not OK.
After this, I torn apart HU and reseated a 32 GB eMMC Micron BGA module from main board, using flux and hot air, but nothing changed.

FSC Codes are good. I have no idea on issue. Seems hardware (eMMC) related.

My (very wild) guess would be that the headunit doesn't get enough current. Maybe a cable is bend/broken or a connection not sitting correctly. Or the problem is with the HU itself. Maybe it has a faulty RAM module... Can you SSH into it and see for messages while it's running?

I have fixed Entrynav.
Issue was with USB stick used for map update - even after full format it was causing HU reboot.
Steps to fix restart loop via Tool32:
1. To stop restart temporarily (till next power cycle): Open Entrynav.prg->select "diagnose_mode"->enter attribute "$10"->double click on "diagnose_mode".
2. To check if map exist: Select "status_lesen"->enter "ARG;STATUS_MAPMATERIAL_VERSION"->double click on "status_lesen"->last line of results window should show saved map (e.g Road Map EUROPE EAST Route 2022-1).
3. To remove map: Select "steuern_routine"->enter "ARG;NAVI_MAP;STR;0x01"->double click on "steuren_routine"->leave car for 10 min.
4. To confirm if map has been removed: Select "status_lesen"->enter "ARG;STATUS_MAPMATERIAL_VERSION"->double click on "status_lesen"->last line of results window should NOT show saved map anymore (e.g Road Map EUROPE EAST Route 2022-1).
At this point, you can cycle power and HU should not restart anymore.
Proceed with map update from USB stick, that is different than one that caused all hassle.
