Chevrolet Repair: Replace radio antenna on 2002 Tahoe, radio antenna, chevrolet tahoe

Question
My radio antenna on my 2002 Chevrolet Tahoe broke off.
The problem I have is that the cable, attach to the mount, disappears somewhere behind the glove compartment. I have tried to put my hand behind to follow the cable. I dropped the glove box down and still can't reach it.  What can I remove in order to unplug and replace the new one.  I can't get my hand up behind to unplug.  What's the trick  

Answer
Hi Don.... There really is no trick, and they are fun to do...you have to unplug from the radio undo the mount and try to pull cable thru... when installing the new one route the cable in a way that you have axcess to it... when building these they never figgure that anyone might have to work on them, they put them together in a way that easy for them...hope this helps
