Any other options that are the same form factor and just wiring harness changes? Also, @SixPapaCharlie, do you already have a WASS position source? Only other advice I can add is to walk over to Trevor and see what he thinks. Better advise is hard to find in NTx
@bnt83 would know for sure, but could it also require an antenna, coax, or GPS antenna change? Not where I can look it up right now.
Not really the case. I installed and integrated my own GTX 335 with zero avionics install experience and no help from outside sources except for the pitot/static and encoder verification tests. Research the heck out of the project and dig in.
yup.....and I too did mine....it went to each box in my panel. Audio, GNS, and GTX...and the gray code....It's not a 2 hr job.
