Wheres the switch for the rear wiper, and where should the wiper sit in the "off" position. mine hangs down below the glass (pointing toward the tail light)

This past week, I drove to/through several areas where the nav told me that it didn't have the data to tell me what was going on. I assume I need an update? Is this a dealer thing, or down-loadable (my disc is 4p)

 

My rear wiper used to sit parallel to the ground all the time. I switched out the rear wiper to the 2010 model and now it sometimes falls to the point that you are talking. It still works great but it is an annoying thing.

I would definitely upgrade your nav disc as it is not a downloadable upgrade. The current disc is 9P. You can order this disc at NAVTEQ Maps and Traffic. You probably do not have to upgrade to a 9P as it is $199, but you might be able to find a used 8P disc on ebay.

 

I would look on the torrent sites for the updated disc. $199 is absolute insanity for a map upgrade that you may not notice any difference with.

The wiper should sit parallel. If not something is wrong.

 

I read that the 2010 wiper arm doesn't have the splines that the 2007 - early 2009 wiper arm. Therefore it could tend to slip from its original position if not tightened enough.
