The reset worked for me - I held down the map and FM button for about 15 seconds and it reset the radio. The traffic then activated itself and I had to re-enter all the radio presets. The traffic will work if you are not on a planned route - it shows up color coded on any main road you are on or around. I live in New England and travel between New York and Boston and find that the traffic is pretty reliable - I would say it's accurate about 80% of the time. However, Google Maps on my mobile phone is definitely much more reliable. I find that the factory navigation will often tell you there is traffic but rarely says why (accident, construction etc.) I was discussing with my wife and we figured that with the cost of yearly upgrades and the 80% reliability, next time we're going to save our money and buy a Garmin with free lifetime upgrades - seems more practical from a financial perspective. Of course, in a Cadenza, the nav is standard.
