Overview

The Metra AXTC-LN29 is a data interface with steering wheel control (SWC) capabilities designed for select GMC models from 2006-2023. It retains R.A.P. (Retained Accessory Power), NAV outputs (parking brake, reverse, and speed sense), and provides accessory power (12-volt 10-amp) and a 12-volt illumination output. This interface is compatible with all major radio brands and is suitable for non-amplified systems or when bypassing a factory amplifier.

It features auto-detect technology for automatic vehicle and radio recognition, as well as the ability to dual-assign steering wheel control buttons. The AXTC-LN29 can also be manually programmed and retains settings even after battery disconnection or interface removal. It is micro "B" USB updatable.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
