Instead of getting the Dynon GPS you might be able to save money and connect your output of your GPS via NMEA to the skyview and use that for both. You don't have to have a Dynon GPS as far as I know.
I purchased the Dynon GPS and will get it installed on the 25 hourly. Don't want to do it myself. I'll get the sensors a little later.
As for lovely Jabiru, they don't seem to understand the requirement of the skyview. When I picked up my J230, the look on their faces when I said where was the GPS and it wasn't till I got back that I discovered the lack of sensors. I emailed the distributor in Horsham and he isn't impressed either.
Another thing, when I pulled the dash to look behind, one of the cables FELL of the mag switch. It was pretty loose, that's my next job.
Anyway, besides that, seeing the Jab and picking it up was amazing. Great plane to fly as well. It's just a pity they couldn't complete the deal with a completely satisfied customer. Felt let down by their replies to this situation.
