Default thank you all

I was certain that the 200 did not have the cam. I'll get back into it and see if that does the trick.

I had considered that a screw may have worked its way loose and was causing the problem. If you experienced that, how did you find/fix it?

The GTN uses a very clever mechanism to pull it in and push it out the rack, the hex screw must be turned all the way to left to push the unit out of the rack and release it, at that point you pull it out. Once you have it out and see how it works it becomes clear.

I was certain that the GTR200 and the GTN650 did not have the cam type lock. I'll get back into it and see if that does the trick. And, the GTN650 still doesn't want to pull free-I am sure that the cam lock is disengaged, the unit pulls out about 1 1/8" and then is catching on something and as much as I carefully wiggle and joggle the unit it won't come free. I'm careful not to pull too hard but I'm pulling hard enough that it ought to come out-???

Hi Jeff,

You might get a good flashlight and look under the GTN 650 while lifting on the unit to see if the pawl latch is striking the instrument panel.

It should not be doing that since the engagement section of the rack is slightly raised above the panel cutout, but perhaps your rack is riding a little low in the panel cutout.

Here is a picture of the latch cutout in the bottom of the rack so you can see what you are working with.

And the removal instructions from the install manual:
To remove the unit from the rack, insert the hex drive tool into the access hole on the unit face. Rotate counterclockwise until the unit is forced out about 3/8" and the hex drive tool completely stops. This will allow the unit to be freely pulled from the rack.

Be sure not to over tighten the unit into the rack. The application of hex drive tool torque exceeding 15 in-lbs can damage the locking mechanism.

Default Got it out!

" . . . rack is slightly raised above the panel cutout, but perhaps your rack is riding a little low in the panel cutout."

That was it. The paw that hangs down on the pivoting latch arm was catching on the lower part of the panel cutout. Fashioned a 'slim jim' from a piece of thin steel strapping band and slid it under the paw to let it slide over the edge of the panel cutout. Out it slid.

Probably going to cut the narrow piece of the panel face that runs across the bottom side of the 650 tray, can't see it anyway - won't know it was there or that it is gone.

Hi Jeff,

Glad you were able to remove these units and figure out how to improve the installation to make it easier next time.

Steve
