What the fak?
You say you have map 8.1 but it tells you map 8.1 is available? What you have is the latest. 8.1 is technically 8.10 and I don't think they made another 810 for you just yet.
NO. What I said is that I have 810.1907 maps and that the 8.10 maps are available for me to purchase. IS there a difference in these?
