This particular model I removed for just that reason,and upgrade to a glass panel.  Its a standard 4 place version with two unswitched aux audio inputs - for things like alerts or tones from other avionics - and a stereo music input.  It comes with the standard faceplate as shown in the picture, as well as a round plate for use in a standard 2 inch instrument hole, the connector, backshell, jacks and insulating washers.  Everything but the wire and I can include the install manual if you need on a flash drive, I believe it is also available on the PS Engineering website.

These sell for about 500, check Spruce or wherever you like, so I feel my price is more than fair for a functioning used unit. I dont have a way to offer a yellow tag or a warranty, it was working when removed.  

Please feel free to contact me with any questions or concerns you might have before you bid. I dont sell junk but I dont do returns either.  I ship via Fed Ex or USPS, whichever is less expensive,  I dont ship overseas and I prefer to use delivery confirmation so someone needs to be able to sign for it.
