You may want to consider Val Avionics. He says that his radios speak digital to the Skyview just like the SL-30. I just bought one of his radios (Val Nav-2KR), but have not tested it in flight yet, since I am more than a year away. The reason I bought the 2KR is because it is a complete remote radio. His more conventional radios are panel mount. YMMV!
Sam,
The Val 2KR is a remote only Nav radio. That means all tuning and volume control needs to be done from the EFIS. Currently SkyView doesn't allow you to tune a NAV radio unless the frequency you want is in the database, and most ILS frequencies are not. We also offer no way to adjust volume nor mute/unmute the audio. So you may find the use of that product to be limited with SkyView. We hope to offer more support in the future, but we can't make any promises when that will be.
Mataylor,
The SkyView GPS can only be used in VFR conditions. If you are VFR enroute, then it is an awesome map. If you are IFR, it's still a great map, but legally you need to be using something else as your primary navigation. If you are OK flying airways VOR to VOR, then you can use a NAV as your primary and GPS as a reference, but you can't file direct-to anywhere.
