In case you hadn't checked an upgrade is available....
not sure if it fixes the missing software keyboard issue though

Edited:
WOOO HOOO yes, it fixes the keyboard issue on the XDAIIs


Also, if I have BT emabled (for my car kit) and also star TT5 with my BT GPS then exiting TT5 does not disable BT on the phone..

My congratulations to TomTom for responding to their users problems.
