Avidyne is no doubt a step forward for future owners. I wonder however if CD should not opt to offer all Garmin ie 530 and 430 as an option, skipping larger display. Would save some bucks and be nearly as functional as wider screen. For SR20 A and B, it would give added backup and functionality at a lower cost. For the hard IFR driver, add a Sandel if you wish. I believe a better use of our hard earned $.
