Accept Screen not responding
Nav screen has the Warning with “Accept” by the lower right button when the beast is started. Recently it has intermittently not responded to the button push, meaning the screen stays in the Warning mode and the radio, etc cannot be used. B/C still scrolls through the items on the dash display. Sometimes if I turn the beast off and remove the key for a few minutes it will start working, but it increasingly is not responding even to that. Garaged, about 170k miles, ambient temps in low 40s F lately but warmer in the garage. All other electronics working fine including seat heaters (which usually seem to be first to go when there is a battery/alternator problem). I put it on a tender to top it off anyway. Any ideas what could be wrong or what to do to get it responding?

Does the unit have some sort of touch-screen calibration routine in he setting? If so, try that.

Not a touch screen. Factory Navigation unit.

Ah right...
My MID unit is like this occasionally. I think it fails to communicate with the data bus. Maybe check the two connectors on the back of the display - ensure they are locked in correctly?

The Nav screen itself is just a simple input device that receives data or sends data back to the originating source.
The OBC is incorporated into the instrument cluster (IKE)...so using the BC button (on the turn signal stalk?) is sending data from the IKE to the nav screen over the I-bus...which is not necessarily connected to the data coming from the nav CPU. I'm not sure the Nav CPU has a reset procedure in the e53...but you can try ejecting the nav map and reinserting it to see if that jogs anything.

After I get the battery fully topped off (tomorrow morning), I’ll pull the head unit out and make sure all cables are clean and tight. Easy enough to pull the nav CD and reinsert it also. If neither of those work, I’m probably at trying to access that button/switch and clean its contacts.

My E46 factory navigation MKIV is set to auto accept. It just shows the accept screen for 8 seconds or so and then gets on with it. Mine is V32 and I think the auto accept started with V27

I wish! Not the case on the E53, it will sit on that Warning screen until you push the bottom right button (“Accept”) no matter how long it is running.

What version firmware are you running? V27 and later should provide the auto accept on all MKIV systems regardless of model.

I don’t recall the version and of course I can’t look at it now. If I get the system past the warning screen I’ll try to find the version. But I’m sure this one never moves past the warning without the button push. I’ve owned it for 9 years and 100k miles, and it worked fine until about a week or two ago, so I’m confident in that.
