USB Port AUX Jack Auxiliary Input Adapter for Chevy Buick GMC Cadillac

In this review of the Topparall USB Port AUX Jack Auxiliary Input Adapter, the bottom line is simple: it is a targeted replacement part for owners who need a direct replacement USB/AUX interface for select GM vehicles from 2015 through 2018. The reviewer found it best for DIY installers and technicians who want a part that matches factory fitment and replaces part numbers 13519224, 13509942, 13510854 and 23496501. It is not a universal audio dongle but a vehicle-specific replacement, so buyers should verify model year and console compatibility before ordering.

Key Features

• Direct fitment: Designed to replace specific factory part numbers so it installs with standard mounting points and connectors on compatible models.
• Wide model coverage: Covers many Chevy, Buick, GMC and Cadillac models from 2015 to 2018, which simplifies sourcing for owners of those vehicles.
• OEM replacement intent: Matches the function of the original USB/AUX jack so phones and media players connect using the existing infotainment system.
• Quality inspection: Each unit is inspected before leaving the factory, which helps reduce the risk of out-of-box defects for buyers.
• Straightforward swap: The adapter is meant for a straightforward replacement process, making it appropriate for basic dash disassembly and reassembly tasks.

Who It's For

This adapter is for owners of Chevrolet Malibu, Malibu XL, New Cruze, Equinox, Camaro, Corvette, Silverado 2500 HD, Silverado 3500 HD, Sonic, Suburban, Tahoe, Traverse and Trax from model years 2016 to 2018, plus compatible GMC, Cadillac and Buick models listed in the fitment notes. It is ideal for drivers who need a direct replacement to restore USB and auxiliary input functionality without modifying the dash or aftermarket head unit.

It is not for people looking for a universal Bluetooth or wireless CarPlay adapter, nor for vehicles outside the specific year ranges and model lists provided. If you need additional features beyond the factory USB/AUX functions, consider a different aftermarket interface designed for that purpose.
