there should be a part you can dump in. Its about one inch deep and as long as the set of controls.

2 parst needed the cupholder itself and the mount, which fits into that slot.
Click on the link below and look at parts #12 and #13 (which replace #14 nav controls).

I just don;t know what is underneath your nav controls, but I assume the same space that is in my C5 A6. Please note, it does NOT hold the X-large cups from McD's!!!<ul><li><a href="http://www.trademotion.com/partlocator/index.cfm?action=getJointLocator&amp;siteid=215021&amp;cha pter=&amp;Sectionids=0,2648&amp;groupid=3396&amp;subgroupid=26 53&amp;componentid=0&amp;make=2&amp;model=A6&amp;year=2003&amp;graphic ID=1

and it has stayed dormant ever since, even if i hit a button. the tabs are a 1 time install btw, so once you snap that unit out its out for good and you need a new casing to snap it in place. (might comme with whatever you replace it with)

Sorry for what is probably a newbie question (just got my RS6 two weeks ago), but what is RNS-E? I keep seeing posts about it (and it seems to be a nav system?), but no pics. Any info is appreciated, thanks!

upgrade to the interior looks and nav function. Replaces symphony II. There is a picture half way down my photos of mine. Look at navplus.us.
