Thanks Greg
I have also posted this on "The Hull Truth" which have Navionics Reps on it, so far no responses from anyone. One thing about this site someone always replies.
From email discussions with Fugawi folks it appears that Navionics is making some changes, not sure if this will affect Navionics High Def chips, based on printed literature nothing has changed. On Fugawi's Explorer Hotmaps, Lake Eufuala, OK and Lake Fork, TX High Def Maps are no longer available along with many others which have disappeared. I am considering the purchase of two platinum chips based on getting some of the high def maps for Oklahoma and Texas.
