Replaced stock JBL headunit today on a 2002 Limited I bought about a week ago. Radio wouldnt turn on at all after checking everything pulled it out opened it up and found about $3 in change and a U2 inspired "Kids Rockaby Lullaby" CD all stuck inside. Guessing a coin broke or shorted something.
Replaced with Pioneer Model:FH-S501BT (Cheapest Bluetooth double din $110) and used the Metra 70-8113 harness adapter ($16).
Used brackets off of stock headunit and audio butt end connectors. Followed harness directions and Pioneer wiring diagram in headunit manual and replaced in a parking lot in about 45 mins. Phillips, 10mm (remove headunit) 8mm (remove headunit brackets), channel lock to pinch butt connectors.
Radio and everything works including antennae and uses factoty amps and harness, did not need to cut or splice any factory wires.
Now no sound/only slight static from rear speakers. Maybe rear speaker amp shot? speakers shot?
Front lower speakers also sound blow pulling door off tomorrow to take a look at everything.
