Remove vacuum sys and install G5 w/STEC 30

Has anyone removed their vacuum system and installed a Garmin G5 HSI to work with a STEC 30? Replacing the directional gyro with the G5. I already have 1 G5 installed.
 
I put 2 G5's in my Navion (with an Stec 50) and eliminated my vacuum system. You will need a GAD29B to connect the Stec to the G5. If you've got the GPSS for the Stec 30 you'll need to remove it and the Heeding/GPSS switch. The G5 provides its own GPS Steering and has a command to switch between heading bug and GPS. The 2nd G5 gives you fail-over redundancy for the AI. I love it and would not go back.
 
GAD29B, not GAD29

Larry,
You've probably already acted on this, but for the STEC 30, be sure you get the GAD29B interface, not the GAD29 which lacks the analog outputs for heading. I have an STEC 30 and can't connect it to any of the Garmin equipment in my plane because it has a GAD29.
