Hi. I have a 2015 Frontier PRO4x. Everything works except the traffic feature. It only notifies me of incidences far away from me, but shows local gas stations, while the traffic flow feature gives me nothing local. I'm at a loss. I've tried everything but the right thing. If I need a new SD card why would this one show local gas, but the nearest incident is an hour away? The dealer wants $180 for an SD card, but if that's it I would have to spend it. Anybody have a clue as to what this is all about?..thank you!

They're overcharging you. Note: It appears that this is the final update for your vehicle, and is from 2018.
