On my original Tracker I had the radio mounted under the dash at my knees...bad spot. I banged my shins more then once while wheelin (I am a rather large fellow!). On my latest 'Kick I removed the rear view mirror and put it there. I like this setup much better. I have no trim panels on my truck (base model), so I put the power and antenna in split loom and ran it down the passenger side pillar. It's not (too) noticable. :-/
Can get pics if you want...
