I'v got and 07 KLE and found an option that works well (may depend what satnav u've got). I use a Navman S30 and did this:
- Got a palstic box from electronics store, big enough for unit to sit in, that has removeavble/replaceable lid. (not sure where you are, Dick smiths are good option in Oz)
- Inserted some foam and cut out space for unit to fit in (some stuff they use in camera cases or the like)
- Cut acces points for power cord and headphone cords (if you use) and from lid to view screen
- Put small aluminium arms off the windscreen bracket, bolts thru side of plastic box will allow it to slide on and fix to brackets.
This puts the gps in behind your screen (i have larger screen, but works with factory one) directly above your dials. Unit is easliy viewable, won't shift, isn't in my way and is protected to a degree by the windsrceen. It's also removeable and simply leaves the 'arms' from the windscreen bracket in place.
I know a picture would explain this easier, but i don't currently have any. Let me know if you need futher info (or pics)
