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.
