The description says it will give more accurate runway position than a 430W (presumably with a GA-35 or GA-37). Why is it so much better?

The 430W and GTN650 output the GPS position in ARINC-429 format, the ARINC-429 resolution is only about 40 feet. Our new GPS resolution is a few feet, NMEA with 4 decimal places resolution. The 430W/650 RS-232 Aviation format is only 3 decimal places.

so to get that accuracy would you have to connect it to the serial port of the EFIS and use the internal GPS as the source? That is, I couldn't connect the antenna to my backup GPS and get the same accuracy because it's a result of the format, not the antenna?
The new GPS Antenna module is actually a GPS and Antenna in the same housing. The latest EFIS software lets you select an independent source for the system location. It will use the AF-GPS for GPS position and GTN-650 for navigation data.

If standalone, how is this interfaced to the EFIS?
rob,
will this work with the 4500?

but it still requires a serial connection to the EFIS then? I'm all out of serial ports unfortunately.
it would be really great if the GPS, ARINC module, ARHS and the transponder could all connect over ethernet. That would give those of us with only one screen a lot more options.
Currently the new GPS will only work with the AF-5000 units.

when will the 4500 upgrade to 5000 be ready?
