Connecting 430W and 496

[StinkBug]

I have both units mounted in my panel, but as best I can tell they do not speak to one another. I'm really sick of having to enter my flight plan twice, as well as every routing change. I'm hoping there's some way to get them to share at least that much. I popped the 496 out of the panel to look at the back and I have 3 plugs coming out of it. One for the antenna, one big round one for power, and the third looks like a MiniUSB and I believe is the XM antenna. Is there another attachment for the 430 or is there a menu setting I'm missing? All this was installed when I bought the plane, so I have no idea what was done. 

 

Thanks!

The round connector also has a serial RS232 connection.  I know it outputs NEMA data, but I'm not sure if it has the ability to do anything else.

You'll need a power/data cable and from there it's fairly simple (google for the manual or instructions - or any avionics shop should be familiar with it).  The 430 can feed flight plan info to the 496 so you only have to enter it once.

I have the worlds most CB MFD by having connected the 430 to a 296.  Single RS232 connection to a single pin on the 430.   Avionics shop did it in less than an hour.   It's pretty great.   I have basic nav info on the 430 and terrain and moving map on the 296 most of the time.

I may have you beat as a CB.

Garmin Aera 500 ($599) with GDL-39 ($599) hard wired together.  Basic NAV data on the yoke with terrain, weather, and traffic all in one display that is larger than the GNS-430.  One audio wire plugged into the Aera and my headset that says "Terrain!" and "Traffic!" to me over my headset.  Less than $1200 and no installation charges from an avionics shop.

Andy, you cannot be a CB and buy Garmin.

Yeah, I started sounding like an advertisement for them, didn't I?

Ditto to what rahill and bradp posted.  You need the power/data cable from Garmin, which has a 496 plug on one end and bare wires on the other.  Power and ground go to the airplane (circuit breaker and ground), and the data cable needs a pin crimped on and inserted into one of the big multi-pin connectors for the 430.  You'll have to configure the 430 to send "aviation data" out whichever RS232 channel you connected via the big connector, and configure the 496 to accept aviation data in.  Sounds harder than it is.  Works great too.  The cable is <$50 IIRC and it would take a shop an hour or less to do the work.

Your avionics shop should be able to do this without a problem.
