G500 SUSP problem w/ 2 IFD 540s

I have a B55 Baron with a Garmin G500 PD/MFD, 2 IFD 540s and a Garmin GFC605 autopilot.  I use Jepp charts and Jepp nav data in the IFDs.  I use Garmin flitecharts and Jeppesen nav data in the G500. 

Problem:  Since the new panel was installed in 10/15 I have received a SUSP indication on the G500 when I pass the FAF inbound (enter the Approach Mode?).  In the past this was a nuisance indication since the 540 was NOT suspended and was navigating correctly. 

Recently, I updated my analog Century IV autopilot (which didn't care about SUSP indications) to a Garmin GFC605 which does care about SUSP indication.  I get the SUSP indication as soon as I pass the IAF inbound. IFD continues to navigate fine, but autopilot will not track the displayed glidepath on a GPS approach with SUSP ennunciated on the G500. 

(Garmin navigators have a soft key you can push to remove the SUSP indication, but Avidyne has no such feature.)  Does any know how to remove a SUSP  indication once it's been enunciated on the G500?  I can switch to OBS (from GPS) mode, but that removes all the approach data from the G500 screen (no glidepath, no course with waypoints, etc.)  Consequently, I have to fly the glidepath manually using the VS or IAS mode of the autopilot. 

Is anyone else getting this SUSP indication who's using Jepp charts on the 540s and Garmin charts on the G500?  I talked to one pilot who has 2 540s and a G500 but uses Garmin charts on both the 540s and the G500 and has no problem. 

I'm wondering if this is a mismatch problem given Garmin wants $2500 to unlock their box to display Jeppesen charts? 

Any ideas?

It just isn't possible to have Garmin FliteCharts on an IFD540.
