The monitor is flickering after sw update

Hi,

I'm really surprised, because I coded a MONO MK4 to COLOR with navcoder, and after software update and reboot there is the following flickering image on the monitor. No response from the mk4 with navcoder, no response to software CD. With another MK4 the monitor is working perfectly.
Any idea?


Thanks
Bombolo

Tryed the usual resets:

Battery disconnect, wait 10min, reconnect

Nav disconnect then reconnect

Make sure no map is in nav during bootup (as a test)

Try reloading OS SW, ensuring the disc you used is error free (measure it!)

Your problem has never happened to me, it looks like a sync issue.
You can see the BMW boot logo, but the screen is not syncing to the nav.

Thanks, but the reset did not help.
If I put an OS disc into the Unit, it spins 2-3 secs, but then nothing happens.
It is the second time, when this problem happens.

The first time there was also a MONO MK4, at that time navcoder was not able to change the monitor format yet, so there was a modified OS disc, with colour navboot file in the mono (BMWM01S) folder. The result was the same: flickering image.

At this time, there was normal OS disc, the mk4 coded from mono to colour with navcoder. Before update the mk4 was frozen, was not responding to OS disc. After disconnect-reconnect the sw update started, the SW update screen and the process bar screen was displayed normally, at the end, the update is complete screen appeared, I removed the OS disc, pushed the right button. Then came the flickering image. Then the mk4 unit is not responding to navcoder or INPA any more. I think the loader part is damaged, because there are no menu screen, no response to menu button. The boot process stops at boot logo phase.

It is very strange, both units were MK4 Mono.

Try following:

1. Use V21 Os. This has a different EEPROM memory map layout. Maybe it will kick the nav into life.

2. If you get it going with V21, then check the boot mode and try reloading V31.
NOTE: BEFORE you use V31, check the OS disc for errors. Measure then with a disc checking program! Do a surface scan!

Thanks, do you mean 21.1 or 21?

I have tried several way, but the only solution was reflashing the unit.

no, I had a navi expert here, who built the flash out, wrote it in a flash writer and built the flash back. It is not an easy work.
