I noticed the new XTR 435 on Facebook as being the latest new model out by Whistler. The only difference i notice is the Traffic Flow Rejection. Am I wrong or is there performance upgrades as well? I have been really happy with my 78se ( minus the annoying false alerts) and was hoping for a whole new platform and new design to purchase this year. Is this all there is new for 2012? I don't want to sound negative but was getting my hopes up for something big?
