07 TL-S Navi Reboot on braking

A small video file demonstration is attached.

I have a 2007 TL-S. For a while now I have the intermittant problem that occurs when either I hit the brake or shift out of park. The symptoms of the problem are that the navi system reboots AND the dash closk display goes blank. Both come back but, sometimes, if I keep my foot on the brake, they stay off AND I can't shift out of park, as if the car doesn't recognize my foot being on the brake.

This can happen several times at one sitting and tends to happen in spurts of 2 or 3 days, with no correlation to any type of weather (e.g. wet, heat, cold).

The local Acura dealer had replaced the navi, which wasn't the problem. They claim they can't do anything else since it only happens occassionally and they can't replicate it and thats after having it for almost a week. The car is under extended warrant and the warranty folks have said that it's covered as long as someone can determine what's wrong.

Has anyone seen this?

The problem has to be located within the vehicle's F-CAN and B-CAN multiplex processor units, it's the only common link between the systems. This isn't something that can be self-diagnosed. Note the conditions that it occurs under (first thing in the morning, after driving, ambient temperature, etc) and try to replicate the conditions when you bring it back in for service.
