• ✅ Wireless Apple CarPlay and Android Auto
• ✅ Faster processors and updated operating systems (Android 10–13)
• ✅ Built-in GPS with offline maps
• ✅ Enhanced audio processing (DSP, EQ controls)
• ✅ Support for video playback and rear cameras

Replacing the factory head unit can significantly improve daily usability, especially if you rely on navigation apps like Waze or Google Maps, stream music via Spotify, or use voice assistants regularly.

Compatibility: What Fits a 2017 Chrysler 300?

Before purchasing any new stereo, it’s crucial to confirm physical and electrical compatibility. The 2017 Chrysler 300 uses a double-DIN (or near double-DIN) sized dashboard opening, but OEM units are slightly shallower than standard aftermarket radios. This means most off-the-shelf double-DIN units will fit with the help of a dash installation kit.

Dash Kit Requirements

You’ll need a specific adapter frame to mount an aftermarket radio securely. For the 2017 model, compatible kits include:

• 🔧 Scosche ITCCR01B
• 🔧 Metra 99-8406G
• 🔧 PAC Audio CRH-CH2

These kits ensure a seamless fit, eliminating gaps around the edges and maintaining the car’s interior finish. Some even integrate with the factory bezel for a stock-like appearance.

Wiring Harness Compatibility

To avoid cutting factory wires, use a wiring harness adapter. The correct one for the 2017 Chrysler 300 is typically:

• 🧰 Metra 70-1758 (also known as the ASWC-1 for steering wheel control retention)

This harness connects the factory wiring loom to the new stereo’s harness, preserving functions like volume, track skip, and voice command buttons on the steering wheel. It also maintains power, ground, speaker outputs, and antenna connections.

Antenna Adapter

Most modern aftermarket stereos come with Fakra-to-Male RCA antenna adapters. Since the 2017 Chrysler 300 uses a Fakra connector for satellite radio and AM/FM reception, you’ll need this small adapter to transfer the signal without loss.
