Default Garmin 330 upgrade?

Just curious, now that I have added an Dynon ADS-B receiver I "want" all the bells and whistles for traffic.
I currently have a Garmin 327 bought just before Dynon came out with their
Mode S transponder. A Dynon Transponder would make the most sense but would leave me with a hole in the panel.
How much rewiring is required to upgrade a Garmin 327 to a 330?
It is physically the same size but I am sure there is a new connector and wiring harness required or maybe just a few wires added to the existing harness.
The 330 will play nicely with the Dynon too from what I understand.

The 330 tray is different from the 327. The 330 is longer. The wiring is different but the differences in your install would not be that major.

To wake up the ADS-B traffic, you need the ES version of the 330 and they cost more. The non ES version can be upgraded for a price from Garmin.

You will have to do your own evaluation of what that hole in the panel is worth to you to have it filled.

Upgrade from 330 to 330ES is $1,200.. that assumes you already have a 330. ... since you only have a 327, it'd be a good chunk more... Going straight to a Dynon transponder instead would leave a lot of money for Avgas...

Default Thanks

Thanks for the input.
It looks like the Dynon Transponder would be the least expensive and best option
considering all the changes that need to be made for a Garmin upgrade.
The Garmin SL30 would be a nice fit for the empty hole but I already have 2 coms. Maybe a Val Nav Radio would fit the bill. $995.-http://www.valavionics.com/product%2...000-VHFrec.htm
I just can't leave well enough alone.

Default Trig TT31

Sell the 327 for 1.2k, buy a Trigg for $2.7k, 1.5k difference. Fits in the same hole, not sure on length. That's my plan, not sure if ill do it this year or not yet.

Default Not to steal this thread

But our EAA club was given a presentation by a garmin rep and he said that the upgraded 330 also requires a WAAS gps. He went on to say that the cheapest WAAS gps they have is the 430. Is that correct?

All ES enabled transponders require a "compatible" certified position source that meet the 2020 mandate requirements in order to be a fully compliant client to the ground stations. Does not matter the brand. Some will use non-compliant GPS's to wake up the ground stations for now for as long as the FAA allows it.

The least expensive Garmin GPS that meets the full compliancy needs of the 330ES is the 400W. The G3X will also drive it as well for now...

Thats the quick and easy version....here is the long and detailed one:

Fixed that for you It would be flawed to assume that every certified position source will be compatible/accepted by every certified ES transponder. I would not bet that Garmin's example will take in any non-Garmin position source.

Yes this is a good and most important point....sorry for the omission....

It is up to the maker of the ES enabled transponder to support a given GPS.

To add further detail to this subject:

"3.3.B(2)

Unless the ADS-B equipment manufacturer has analyzed the interface between the
position source and the ADS-B equipment you are installing, and specifically listed the position
source in the ADS-B equipment’s installation manual, you must provide an analysis of the
interface between the position source and the ADS-B equipment which demonstrates that the
position, velocity, position accuracy, position integrity, and velocity accuracy information taken
from the position source is properly interpreted by the ADS-B equipment.

Note: This analysis will require engineering design data
from the ADS-B equipment manufacturer and the position
source manufacturer."

This pretty much requires that the ES enabled transponder manufacturers must formally support the position source used. Just because it may work if connected won't cut it unless that position source is specifically listed in the installation manuals of the ES enabled xponder....I doubt the manufacturers are going to give up their engineering design data for both the GPS and the ES enabled xponder.....

Although not officially announced, Dynon will complement their arrangement
with a certified GPS in the future.
In the meantime the current version of their GPS will wake up traffic targets
when installed with their certified and compliant transponder.
We are still 7 years away from the 2020 target date.
I don't need to upgrade anything at this point I am just looking into the future and trying to lay out a plan for the eventual mandate of mode S and ADS-B
compliance.
