Radio Replacement Help

I have a 2008 Tundra, SR5 with JBL speakers and amp. I am trying to replace the stock 6-disc radio A51828 (model 86120 aa160) with a navigation / backup type radio. I am struggling to find any compatible harnesses or clear diagrams on my current wiring. Any suggestions on replacement radio models or harnesses? Also, any videos or ideas on how or where to fish the backup camera cable through the dashboard / firewall would be helpful. Thanks from a beginner!

 

Welcome to the forum.
You can find your wiring diagrams here..

As to fishing the camera cable, there are plugs in the floorboard of the front seats you could use.

Good luck..

 

Crutchfield is your friend- be sure you’ve ordered/ have the correct harness for your specific OE system (with JBL).
