Same can be said for Dinardi (jester) who basically bans anyone from the 3dr solo group on facebook when they question anything he posts. Must be nice when you have the power to control what is being said, posted or asked at your fingertips and no one will stand up to him. You also as a member can't post items for sale or a new product you develop in that group unless its approved by admins but IMP concepts which is owned by an admin of that same group post his items for sale and coupon codes to his site all day as "admin approved".
Fwiw, the mro listed here is a direct replacement to the stock gps, but afaik the ublox neo m8n has been used in apm since the dawn and can be oe found for $20..you'd just have to figure out the pinout and wire it accordingly and mount it.
