496 GPS Removal

KRAUSEGB · #1 02-17-2012, 11:00 AM

Is it possible to remove the 496 GPS from the panel without removing the avionics cover piece. I know there is a release on the left side, but it looks like I would have to remove a lot of material from the panel opening in order to get a screwdriver into that release catch.
Anyone have some thoughts on this?

There should be (IF it was built according to plans) a small hole to the left of the 496 that one would put a tool into, push straight in and the 496 should release from the stock Garmin mount. If there is a hole there, try a welding rod or coat hanger or whatever is stiff enough and small enough to get in there.

If you have access to the plans, look at the page where it was built and you see what I am trying to describe.

Remove the D180. Reach behind the 496 to disconnect wires & assist removal.

GPS mounting is on PAGE 42-12 available here:

The GPS may or may not be easily removable, depending on the installation.

Thanks Guys,

In looking back at my build log, I see that I had circled this step to do later
if I needed to. Now I guess I need to!!

Thanks Again

I'm trying to remove my GPS 496 from the panel to update the unit and I'm unable to remove it from the docking device.

I've looked over installation pages 42-12 and 42-13 to refresh my memory of what it looks like behind the panel.

So at this point I've removed the D-180 and can somewhat get my hand behind the 496. Do you push the release clip in from the front side and at the same time push a rod through an open hole in the backside brace pushing the unit out? I can't believe this is the process!

For those of you who have removed the 496 from the panel, I await your suggestions.

Thanks

There is a sliding lock on the hook that must be slid toward the nose of the aircraft. Then you can pull the catch arm away from the GPS an pop it loose. I didn't set mine up for removal from the front, and the last time I removed it (about a week ago) I puzzled over how you get it out if you didn't enlarge the opening. I ended up removing the whole cradle to get it out.

I disconnected the XM antenna and plugged in a USB cable that I ran through the avionics bay deck. I wasn't using the XM anyway, so it was no issue. Now I can update without removing the unit. The cable is velcroed to the deck bottom near the POH tray when not in use.

Slide a pick in the small hole to the left of the unit and push inward and if you clearanced the unit sufficiently during the installation, it should pop out. As I recall, I did spend a fair bit of time making sure the unit would come out for me without removing anything else. I would think that removing the D180 or the AP74 would enable you to get it out.

I've tried everything I can think of to remove the unit but no luck. I can release the lock on the left (pushing a rod through the small hole) but I just don't have enough clearance around the unit for it to come out one edge at a time. Soooooooo, (I didn't want to) I'm going to take the top of the instrument bay off and access in that fashion. I can guaranty you the next time the unit has to be updated, it will easily come out of the panel or I'll have an external connection port.

Thanks for the suggestions.
