Replace/Upgrade your old 2014-2018 GMC Sierra & Chevy Silverado radio with a new one that integrates with Apple Carplay and Android Auto 13. I'll also show you how to retain the factory OEM backup camera using the PAC Reverse Camera Retention Wiring Harness (GM51). Furthermore, this install retains the factory steering wheel audio controls. This install is for a 4" or 8" radio screen I04 with no Bose system. Bose systems require an additional decoder purchased separately from the aftermarket radio manufacturer. The 7" factory model I03 uses a different wiring harness, which is included within the aftermarket radio. *Note that some plugs, wires, and connectors will not be used and will stay unplugged within the vehicle. Tools Needed: Drill (For faster installation) - Optional 7mm Socket (Optional) 7mm Offset Wrench T15 screwdriver or bit Auto Trim Pry Tools (Strong straight & curved edge) Electrical Tape (To secure the RCA and Micro USB) Short zip ties (To secure wires) I've replaced my old factory stereo with the AWESAFE 13.1 inch Car Radio Stereo 4GB RAM+ 64GB ROM. The unboxing of this product is also shown here. Links will be updated soon. The only gripe I have for this product is that the steering wheel control for playing the next song or the previous one, is inverted. The app to map the steering wheel control doesn't detect any inputs so you can't set the controls. However, everything else works just fine. This product was also installed in my friend's truck similar to mine but with no issues. ⏱️VIDEO CHAPTERS⏱️ 0:00 Unboxing 3:54 Trim & Radio Removal 4:45 Reverse Camera Retention Wiring Harness Install 5:48 Chirp Installation 6:01 Removing Thermostat Controls 6:11 4g Antenna Installation 6:32 Steering Wheel Control Wire Installation 7:49 Mic & GPS Antenna Installation 8:22 Stereo Wiring Connections Explained 10:50 Stereo Trim Reinstallation Procedure 12:02 Basic Use and Functions of New Stereo Support me by giving a sub if I helped you!
