Hi all. I was wondering whether it is possible to put the n770 in the n800 mounting kit.

I have both a n770 and n800, and use my n770 as sort of a backup to the other, eg in case I forgot to charge the n800, or in case I am going into a rough area, where I appreciate the included hardcover on the n770. I am interested in buying the navicore package for the n800, and using maemomapper on the n770 (since the product activation is apparently bound to a single device).

Therefore, I am wondering just how different the cr81 and cr86 are. After seeing this old post on thoughtfix's blog : http://tabletblog.com/2006/01/gps-arrived.html
I am wondering whether they really are not interchangable, eg. is it really not possible to put the n770 in the n800 mounting kit?
