I just went through the process of paying for a new map (north america) and went through all the steps where it said it was downloading. Then after a very long time it gave me a green checkmark saying the download was complete but gave me an error on the install line. Something about the device not there or something, I can't remember. But now what do I do? I just paid for this map and it's not on my device. Please help so I'm not out my money.
