I have a Garmin 3760 sat nav and I have trying to get fm traffic via a GTM 36 TMC receiver.
The TMC receiver has a mini usb plug.

The 3760 sat nav has a micro usb socket.

I have used a mini usb socket to micro usb plug adaptor and thought that this would work ok.

I can not get the satnav to recognize the receiver even though the TMC receiver works on the 1200 series Garmins.

When I plug the receiver into the 3760 sat nav , I get no traffic icon.

Any suggestions ?

Should the arrangement I have work ?

Thanks.
