Just wrapped up this install on a 2018 Chevy 2500

Installed a Sony XAV-AX8500 floating touchscreen radio and it completely modernized the interior. Huge upgrade in sound, usability, and appearance.

✅ Wireless Apple CarPlay
✅ Wireless Android Auto
✅ Large floating HD display
✅ Retains a clean factory-style look

This dash setup fits the same body style GM trucks from 2014–2018 including:
• Silverado 1500
• Silverado 2500HD
• Silverado 3500HD

If you’ve been thinking about upgrading your factory radio, this is one of the best options available for these trucks.
