: Intermittent problem with RB1 nav. radio

I've been feeling out my new WJ and I've been having a problem with the RB1 system. Every once in a while (about 1 out of 10 starts) the screen on the unit will not initialize. The radio comes on and I can adjust the volume, but the rest of the buttons do not respond. I can't change the station, eject the drive, etc. and the screen is black. Sometimes it will work again after 30 minutes of driving, sometimes not until the next day. When it does come on everything works fine.

The frustrating part is that I can't reliably reproduce the problem. It seems completely random whether the unit will work or not that day. It happens whether or not the Nav disc is inserted or not, whether the unit is in the 'on' or 'off' setting when the engine is started, etc.

I'd rather not lay out the $ for a new one, has anybody seen this problem before? Is there a fix?
