Why Bob? I'm happy with the SL40 and would be with this new radio. I'm not real happy with the cheap intercom the -12 comes with, no loss there maybe.
I agree with you, Bill. I'm happy with the SL-40 - at least after SV 6.0 took over control of the radio. I REALLY, REALLY, REALLY like that feature! Did I say I REALLY like that feature?
Since I have it, and it works, I'm not going anywhere with my ship - radio-wise. So, this is sort of moot for me (and you.)
I agree with you also about the Intercom. The SL40 has an Intercom capability and I'm not sure why Vans chose not to use it. I left my Intercom and ELT controls on the RH panel with the glovebox, so I didn't have to do a lot of rework..
The problem with Vans spec'ing this new Garmin is it sort of locks you into Vans ideas for radios. You could switch after the fly-off period, but then you've got a lot invested in an almost new radio that has now become "Used." I don't think the radio should really be part of the ASTM Light Sport Specification, nor does it affect the basic airworthiness of the airplane.
If I had my druthers, I'd prefer Vans avionics order form offered you a radio choice of A-B-C, like the menu in a Chinese restaurant. Then you could go Garmin or Dynon or even something else.
Personally, I would have preferred not to have purchased the SL-40 - I wanted an SL-30 Nav/Comm instead. The SV accepts the inputs from the SL-30.
In general, mixing and matching avionics vendors often has sub-optimal results, and when there's a problem, usually results in a lot of finger-pointing. The existing lashup has four players Dynon, Garmin, FlightCom, and Vans. Going with the new Dynon radio would have minimized that effect.
Actually, I'm not really sure why Vans chose to be the middle-man (via their 50000A Control Box) in this daisy chain. The SL-40 can be hooked up directly to Skyview without ever passing through the Control Box. This problem manifested itself recently when SV 6.0 came out and added the radio control - but there were missing Vans wires if you recall. SV control of the Garmin could have been a direct one-to-one hookup.
