I use my Kenwood TM-D700 in what they refer to "Locked" cross band.  I
transmit on the 440 band with my HT into the TM-D700 in the car.  It
retransmits on the input to the local repeater on 2-meters.  I listen
to the output of the 2-meter repeater directly with the HT.  

_In_most_cases I've found the two way cross band to be almost unusable
as it requires the repeater to drop before you can transmit. When
things are really busy with emergency operations such as weather
watches or a busy traffic net it's been next to useless, but the "one
way" works very well.  Possibly there are rigs that operate cross band
that don't require the repeater to drop which would be really nice.
