Thread: No more Trafficmaster TMC in the UK

They do point out this:

Older Bluetooth-capable Garmin navigators are compatible with the Garmin Smartphone Link app, and older Wi-Fi-enabled Garmin dash cams can access video footage through the Garmin VIRB app.

One has to try to see if it will work or not.

But Like I said if this does not work there are other Traffic app out there or GPS app for the smartphone.

I know users who use both their older Garmin or TomTom and a smartphone GPS at the same time to give them traffic or speed camera alerts.

As for the 660 manual there is nothing in there that said it will not work.
If you can make phone calls one just has to try it out.
