looking for a GPS map that works on my Garmin Legend C, that is detailed enough to allow for off the main road bicycle rides. I spent enough on the GPS without now spending money for a good map.

That can be bought in stores. The 350 can only be bought online refurbished.

The specs seem similar but I heard the 760’s antenna was less sensitive but that it improved other things like letting you know if your destination was on the left or right side of the street.

On pcrush.com, I ordered a Garmin c340 navigation system. I didn’t know this, but it came to me refurbished. I am in New York, but it says that I am in Kansas and I also never configured my system because somebody else put in their own settings before me. I also get horrible reception because the system thinks I should be in Kansas. I tried to reset it by removing the frame and pressing the reset button, but it didn’t solve my problem. What should I do?

Most satnavs have a list of options to plan routes following various rules - fastest, shortest, avoid motorways, avoid tolls etc.
A congestion charge is a toll. Select avoid tolls. Or just pay the charge. Maybe avoiding the zone could be more expensive in fuel.
