I have 2.0 and it doesn't seem to want to work. I would even consider getting a copied one to see if it works and then going out and buying the real thing. I just don't want to buy one and then to find out it was my nav system that is messed up. I would love to find someone with 4.1c part number 20857425. PLEASE let me know if anyone can help me out!!!
