Hi: I was wondering if there were SMA's for the GPS, if so how much are they? Can I upgrade from version 1 to version 3 with a purchased SMA? If I purchase SMAs and wait till a new GPS is released for the new BN, can I get the new GPS cheaper especially sense I have it already? Also as for the warrantee, what's the deal with the price of $500 that's very expensive. I'm not renewing mine cause I'd rather spend that money the SMA's. Sarai D. Bucciarelli
