I have the Aera 660 mounted on my panel. It talks to a remote GDL 50R. I love it. Great information from the unit. Weather, traffic and TFRs. Easy to program. I also have it set up to talk to the G5s.

I think the subscription for navigation data is $150/year. The software update previous to the last software update gave me some fits but with the latest version I've had no problems.

$550 is a good price for this unit.
