Navigation "CAUTION" startup screen will not go away

[mtrot]

For some reason, that CAUTION screen that appears when starting the car will no longer disappear upon depressing the round control knob like it used to. Also, with that CAUTION screen remaining on the display, the knob will no longer change the radio stations when you rotate it, nor will the navigation map appear on the screen. I just disconnected the batter for about an hour in the hopes that that would reset the system, but when I reconnected the battery, there was no change. Has anybody else had this situation, and, if so, what was the solution? I did a search here, but did not find anything on this. Thanks much.

Could be an issue with the knob. Lots of info on the forum regarding failures. Here is one of them.

Control Panel Knob Problem

2010 genesis sedan 4.6...having problem with DIS control knob. Works fine, left or right. Pressing the knob in is a problem. Press in at least 10-20 times to get it to do anything. Question: do I have to replace the whole unit or just the knob itself?

Thanks, based on info in a couple of threads here, I tried disconnecting the battery for a while, as well as pulling a couple of fuses while the car was in ACC mode but engine not running. I'm not sure what was the cause, but the CAUTION screen did clear afterwards. As to the functioning of the control knob itself, I'm not yet sure how it's working.
