Looking for information on the labor to do the upgrade. I'm upgrading from a GTX327 to a GTX345. My panel includes Garmin 430 WAAS, 2 G-5s, and a GFC 500. What can I expect for the number of hours I'll be asked to pay for the upgrade?
 
Tray swap. Power and ground wires (already there), position wire from 430W, air data wire from G5. Three hours? Plus a flat fee for the appropriate certification with the test box. More if you want to hardwire traffic info, audio, etc.
 
I did this last October for a GTX345 w/ WAAS from a GTX327 w/ GDL82. Receipt attached.

Thank you very much for sharing. Your numbers are in line with the 20 hrs, I was quoted by a FL based avionics shop. Seemed like a lot, but I have no experience to say one way or the other.
