I don't have that option bought it a long time ago. Too be honest I do like the unit and never had any problems with it and would recommend it to others.

Did you try to downgrade your unit FW and then update it back to latest FW?

p.s.
With gcd for type 3 Angelo and i play with gcd but can't find thread where angelo write complet procedure, maybe Angelo or Caty can find this thread or maybe Angelo can modiffy your gcd and then you can try repair GTM.

Yep, the nevi 3598 works fine. Just the GTM70 will not lock onto any traffic signal. Looking at the developers menu its says something like 15 Finding Country. In the menus when with the traffic cable connected it says not supported. Placing the old GCD file back on the unit I still get Garmin Express saying to update. What I can't do is force the old 2.00 back onto the GTM70.
