Help! Buttons Extremely Slow To Respond 07 Camry Hybrid

Ok..now this is weird... (IMG:style_emoticons/default/sad.gif)

My 07 Camry Hybrid starting acting strangely. For the past week, every control (including steering wheel buttons) take *forever* to react.

When the car is started, the navigation system will come up fine but pressing a button, like destination won’t respond for several seconds (sometimes as long
as a minute). The same holds true for the phone menu, onscreen controls for disk, side panel buttons and everything else. Even if I use the steering wheel to call up the phone menu for example, it takes several attempts before it works. And it seems to be getting worse. We’re not seeing any errors on the screen either.

Has anyone else seen this problem? Does it require a “master reset” or something?

We bought the car at Carmax about two years ago and purchased their extended warranty. If necessary, we may need to take the car to them but before I
do, I thought I’d ask and see if anyone else has experienced this problem?
