The seller did post a number of images for the part that was listed. The gotcha is that the part that arrived is not labeled the same way as the part that was listed. Since the device also has issues, the big question is if it has any connection to the part in the listing at all. The seller seems to have been doing GPS stuff for a while. He also has a very good approval rating. My guess is: this isn’t the first time he’s seen a bump in the road. I’d bet he’s got the ability to check this and that out to see what is what. The seller *does* matter when you buy this stuff. That’s true no matter what you are getting. No matter how good they are, problems do come up. The question is always how well they address them. We tend to dump pretty hard on these guys. I’m not sure that’s always warrantied.
