i woudl suggest you to fork out some pennies and get the 3400.... its a good unit especially for the WJ's where these is no intruding place to mount..
TX3400
Uniden has one with the detatchable face like the 3400 as well..
UHO13
the only reason i didnt go for the 3400 is that i didnt have the $$$ back in those days....
cheers
