GTX 335 vs 345

[Ted Ricci]

I have a 530w, flightstream 210 and a gtx335 (which was installed before the 530/210 combo). I'm looking to see: a) is a 345 just a simple swap for the 335 or a rewire job, or B) how can I add weather and traffic to the 530 without a 345?

TIA

I believe you don't have to re-wire the existing connector but the 345 has an additional connector for ADSB-In besides the ones that's already there.

It does involve additional wiring, but it is not a major update.

GTX 345 is my favorite ADS-B In/Out transponder
You can see weather and traffic on displays of certified systems or MFD
and also can see this info on iPad, aera 660/795/796 portables via buil-in bluetooth

What additional wiring?

The GTX 335 has no outputs of traffic and FIS-B, so these signals need to be added to the connected devices of the GNS430W and the FS210. The GTX345 adds two wires between it and the FS210 using RS422 port. This is to add the AHRS, TIS-B and FIS-B into the BT that already contains the flight plan transfer, GPS from the GNS430W. The GTX-345 also adds three wires to the GNS430W for ARINC 429 out and RS232 out. This adds the FIS-B and TIS-B data to display on the GNS 430W. Also, the GNS 430W will probably need an unmuted addition to the audio panel if it is not already there. How much labor is a function of what needs to come apart. Worst case is the FS210 is not located behind the panel, but is remote in the rear of the aircraft.
