tailBeaconX and AV-30

Hi Larry,
I have the AV 30, which is very nice. Needs to be placed on the panel directly ahead, I’m looking hard on up grading to X as I;m going to redo the panel this fall, and was considering a new small transponder
(Trig) but with the credit I would come in for less money and save panel space also.
from what I understand the rebate is applied, once they have your old tail unit. Not to clear on their web page.
