OEM JBL stereo replacement

I'm happy enough with the original system and just want to replace it due to the radio now not being able to continue to lock on signals consistently. About every 15 seconds the channel will change to slightly "off" the original station and come back after about 5 seconds.
Question is, where do I find a replacement? Everything I look at is about upgrading.

Thanks

 

Either a pick-n-pull or ebay. Just grab the part number for it and search.

 

Here's a couple to look at -

Hey, I just pulled the 6 disc changer out of my 2002. It was working fine as far as I could tell, though I didnt use it much. I was planning to list it for sale on this site but I am not a 30 day member yet. If you want it, I'd send it for shipping + $5. PM if interested.

 

theyre selling them for $100! damn, im gonna grab mine out of my garage and post it up. didnt think anyone would want a 16 year old HU
