Don't know if this came up yet...
The Verizon Treo 650 update fixed my blue tooth compatiblity issues with the M35 car kit.
I could make calls manually before, but could not use the voice command features with the phone. (kept getting phone disconneted message)
With new version 1.05 for Verizon. Compatibility issues seems to be corrected.
