I've used my 6310i successfully on an old CARK-91. The only thing I can
suggest is that if the phone has been dropped, the contacts at the bottom
might not be working all the time. Usually this causes a more intermittent
problem but if your handset is refusing to switch into "CAR" mode (which
displays a car icon in place of the profile name on the 6310i) then perhaps
you are running an older version of the software?

A while ago there were some cheap car handsfree kits that were incompatible
with the 6310i until the software was updated from the first release, it's
possible you have a similar problem.

Have you tried cleaning the contacts on the base of the car kit and the
phone using say, emmery paper and/or a wire brush etc? It's possible the
resistance is out purely because of chorrosion on the contacts.
