17-21 Replacement 8.4in Uconnect 4C UAQ LCD Touchscreen - Direct Fit

In this review of the 17-21 Replacement 8.4in Uconnect 4C UAQ LCD touchscreen, the bottom line is simple: it is a focused replacement part for owners who need a direct-fit 8.4in touchscreen for Uconnect systems and want responsive touch performance without replacing the entire head unit. The reviewer found it best for mechanically straightforward installs and for restoring daytime functionality and clarity to compatible Dodge, Jeep and Chrysler radios, while noting a few durability caveats customers have reported.

Key Features

• Replacement compatibility: Designed specifically for Uconnect 4, 4C, UAQ and UAS 8.4in radios so it fits the factory opening and connects to the original interface without major modification.
• Broad vehicle fit: Covers many late model vehicles including Jeep Grand Cherokee, Cherokee, RAM 1500/2500/3500 chassis cab, Chrysler 200/300 and Dodge Challenger, Durango and Charger, making it useful for multiple platforms.
• Rapid touchscreen response: With sub-8ms response and conversion under 20ms, the panel delivers noticeably quick touch feedback for menus and navigation controls.
• High touch precision: Uses the P/N LA084X01(SL)(01)(02) LG replacement panel to achieve better than 1% error in touch accuracy, which keeps small on-screen controls reliable.
• Upgraded durability: Toughened surface hardness and anti-chemical treatment reduce scratches, glare and fogging, preserving visibility in everyday use.

Who It's For

This replacement is aimed at DIY owners and independent installers who need a direct-fit LCD touchscreen for an 8.4in Uconnect head unit in supported Dodge, Jeep and Chrysler models from the 2017 and later era. It is ideal for those who want to restore a cracked, unresponsive or low-quality screen without buying a full OEM radio.

It is less appropriate for buyers who expect a new infotainment feature set or factory warranty coverage; if you need a full head unit upgrade, integrated GPS repair, or long-term OEM-backed support, a full unit replacement or dealer service may be the better path.
