Hi All

With Reference to Traffic Receivers on newer Garmin Units,

Some are built into the unit its self and supplied with a standard 12v looking power cord which also acts as the antenna,
and other units have the traffic receiver in a little black box attached inline on the 12v power cord, These are more chunky and have 2 wires running through them.

So before you rush out and but a traffic receiver for you unit do a simple test

Go into Settings down to the bottom and select device then select About and you will see this screen (below)

NOTE. 3rd line down "Built-in traffic receiver: Yes"

Not mentioned on any of the Garmin sites so thought I would list it here for other confused users
