I have not put it in an '06, but it works fine in 05's w/Bluetooth and Assist. I can't imagine that they would change the radio to that degree for the last year of a model run...

As for the connectors -- they are in the cargo area driver's side-compartment (at least in the USA) and are usually wrapped up -- including the ends -- in a black fabric tape on the floor of the compartment. They might be tucked in with other wires. There will be 2 connectors. One is a 6-pin and the other is a 3-pin, both have a rectangular head.

Statdoc is right -- it will not work w/Nav radios.
