Axxess Introduces a New Radio Replacement Interface and Amplifier Retention Interfaces

Jan 6, 2020

Holly Hill, FL – January 06, 2020 - Axxess® by Metra Electronics®  is introducing a new radio replacement interface for GM, a new amplifier retention interface for Ford A2B amplified systems and an amplifier retention interface for Mercedes MOST25 systems at CES. The AXDIS-GMLN31 is a data interface with steering wheel control retention for non-amplified systems in select 2019-up* GM vehicle applications and is part of the AX Series. It provides NAV outputs for parking brake, reverse and speed sense, provides 12-volt/10-amp accessory power, in addition to retaining R.A.P. (Retained Accessory Power), chimes, and audio controls on the steering wheel. This interface also retains balance and fade (except in OE systems with fixed level outputs), and is Micro “B” USB updatable. It features an improved initialization process with a reset button located between the two Micro-Fit™ connectors.

The AXM25-MB1 is an amplifier retention interface for select 2012-2017 Mercedes vehicles with a MOST25 amplifier. The AXA2B-FD1 is an amplifier retention interface for select 2017-up* Ford models with an A2B amplifier. This interface is designed specifically for amplifier retention and must be used with an Axxess Ford radio replacement interface. Both of these new products bring easy integration solutions for installers replacing the factory radio in GM, Ford or Mercedes vehicles. The AXDIS-GMLN31, AXM25-MB1 and AXA2B-FD1 will be shipping soon and can be seen on display at CES 2020 with Metra Electronics at booth 5211 in the North Hall of the Las Vegas Convention Center. New Axxess products can also be seen online at starting January 7.
