I am planning the upgrade of a Piper Navajo panel. I wouldn't mind
spending the money for "cutting edge", but it is not clear what is
avialable and the infrastructure to support it. Could anyone provide
informed councel on EFIS or other certified options?
My questions are along the following:
1. Should I install Skywatch/Mode S or wait for ADS-B (I fly east
coast)?
2. Ditto on satellite weather?
3. Are any of the "economy" glass panels certified for retrofit?
I curently have a Garmin 530 and steam gauges.

#1. Since you already have the 530, I would go for the GTX330. I
imagine the E. Coast probably has the best TIS coverage of any place
in the US.

#2. Sat weather is awesome. Although, I don't think you have any
good options right now with the 530. I would consider getting a
tablet PC + WxWorx. If you don't want to mess with cables, get an
Avidyne or other display that is capable of displaying XM weather.

#3. I don't think so.
