I don't believe it has to do with the harddrive which I at first suspected. I have upgraded the DMS to 80G using the patch. Similar issues occured on the 80G drive.
It must be something with the communication between the HU and the Keg. Before, I used the KEG with an Kenwood HU. The same problem occured after some weeks. I than installed the KEG in my Audi, patched the box and upgraded the DMS and bought the needed cables from ebay which are of a different kind than the original Kenwood cables.
As I said, during operation everything works properly. Problems starts when I start the car anytime in the day. Only very rarely when I push to many buttons to fast it will lock or controls cannot be used. I suspect there the issue.
When it is in lock state, I easily get it working by removing the Cable and placing it back. It feels to me like a buffer is flushed when I remove the cable. But it will not surprise me if it all has to do with the booting of the CPU. Well how to fix that?
I know for the Audi HU you can choose several settings, maybe I should play with that.
Any more ideas welcome.
