Axxess® Launches New Integration Accessories at SEMA

Oct 31, 2023

Holly Hill, Fla. Axxess® by Metra Electronics® has expanded its product line to include additional vehicle applications for popular integration solutions and will showcase these new products at the SEMA show. Launching at the show are new vehicle-specific DSP packages, MOST25 audio system interfaces, Total Control series interfaces, a backup camera retention harness, interfaces designed for Pioneer® radios, OnStar® retention interfaces, and more. These new automotive accessories will be displayed from October 31 to November 3 in the North Hall of the Las Vegas Convention Center at Metra's main SEMA Show booth, #10539. These new integration accessories are designed to help installers deliver upgraded sound systems and everyday convenience to drivers.
DSP Packages
Axxess's new DSPL and DSPX packages include applications to fit select GM vehicles and a much-anticipated integration for 2021-up* Teslas with amplified systems. This package will be among the first of its kind in the industry, designed specifically to upgrade the audio system of this vehicle brand. These DSP packages include amplifier bypass harnesses and feature combined digital signal processor and data interface technologies that allow installers to upgrade their music experience and customize their sound system. The DSP is designed to integrate with factory audio systems and retain factory chimes and voice prompts. Axxess's DSPL series provides six channels of output and a 15-band graphic EQ per channel, while the DSPX series features 10 channels of output and a selectable 31-band graphic EQ or 5-band parametric EQ per channel. Both products offer selectable crossover slopes, feature independent equalization for each output, and the ability to read, write, and store configurations for future recall. All tuning is done via Bluetooth® wireless technology in a free downloadable app for smartphones and tablets. The Axxess app is compatible with both Android® and Apple® devices.
MOST25 Interfaces             
Axxess is debuting new interfaces designed for vehicles with MOST25 amplified audio systems. These interfaces provide accessory 12-volt power, parking brake, reverse, and speed sense NAV outputs, retain audio controls on the steering wheel, and are micro “B” USB updatable.
New applications include the following vehicles:
●      2004-2013 BMW 1 Series and 3 Series
●      2006-2012 Land Rover and Range Rover
●      2005-2009 Land Rover 3 and Range Rover Sport
●      2003-2008 Mercedes CLS, E, and SLK
●      2006-2011 Mercedes GL, ML, SLK, and E
●      2002-2007 and 2007-2010 Porsche Cayenne
●      2004-2009 Porsche 911, Boxster, and Cayman
Total Control Interfaces               
Two new interfaces have been added to Axxess's Total Control Series, designed for use when replacing the radio in the 2009-2016 Porsche and the 2016-up* Mercedes. These products utilize patented auto-detect technology that automatically detects the vehicle type, radio connection, and preset controls while allowing the ability to dual-assign steering wheel controls. They provide wires for multimedia radios (parking brake, reverse, speed sense), accessory power, a 12-volt illumination output, and retaining R.A.P., balance, and fade. The Axxess Total Control Series is a universal solution designed to work with all major radio brands and can be manually programmed for most vehicles. They will retain memory settings even after battery disconnection or interface removal.
Backup Camera Retention Interface
Axxess will also display a new backup camera retention interface for the 2008-2015 Volkswagen. This interface allows the factory camera to be used with an aftermarket radio. A convenient, plug-n-play design saves integrators time since cutting wires is not required for installation.
Pioneer Radio Interfaces
Axxess is introducing various vehicle-specific interfaces at SEMA for installing select Pioneer® radio models. With these interfaces, vehicle information and settings controlled on the factory screen are retained, displayed, and controlled on the Pioneer® touchscreen. These displays, such as HVAC functions, would otherwise be lost after replacing the head unit. The built-in integration technology from Axxess also retains safety chimes through an included offboard speaker, retains audio controls on the steering wheel, retains R.A.P. (Retained Accessory Power), and provides 12-volt 10-amp accessory power and NAV output for parking brake, reverse, and speed sense. These interfaces allow for auto stop/start override, if equipped, and the retention and adjustment of the OE Personalization Settings. Total Control interfaces are installed with easy plug-n-play connectivity, and a radio antenna adapter and an antenna adapter for GPS are included. New interfaces launching at SEMA include applications for:
●      2013-Up* Chrysler
●      2021-Up* Chrysler
●      2010-2017 GM
●      2014-Up* GM
●      2019-Up* GM
●      2011-Up* Ford
●      2020-Up* Ford
●      2015-Up* VW
OnStar® Retention Interfaces
Two new interfaces will debut at SEMA designed specifically for the 1997-2005 Cadillac with amplified systems and the 2004-2007 Saturn with non-amplified audio systems. These interfaces will retain OnStar® functionality, chimes, balance and fade, and R.A.P. (retained accessory power). They also provide NAV outputs, including parking brake, reverse, speed sense, and 12-volt 10-amp accessory power.
Turn-on Interface
The AXTO-MAX interface is designed to fit 2016-up* Nissan Maximas with amplified systems. Interfaces from this series are intended for vehicles that require a data signal to turn on OEM amplifiers, retain rear seat entertainment, and more. This new interface will retain the factory backup camera, the audible parking sensor warning, the factory AUX-IN jack, and balance. It also provides accessory power (12-volt 10-amp) and wires for multimedia radios (park brake, reverse, speed sense). This interface can be paired with the AXSWC steering wheel control interface (sold separately), and a pre-wired AXSWC harness is included.
Add-a-Sub Interfaces
Various new interfaces from Axxess's Add-a-Sub series will be introduced at SEMA to fit select Chrysler, Ford, and GM vehicles. These interfaces have 2-channel non-fading 5V RMS output, a fixed low pass frequency of 234Hz, and 250mA remote turn-on output. There are options designed for amplified and non-amplified vehicles, and a bass knob & vehicle-specific harness are included. New applications to be displayed at SEMA include:
●      2007-2018 Chrysler
●      2013-Up* Chrysler
●      2007-2017 Ford
●      2013-2021 Ford
●      2022-Up* Ford
●      2014-2019 GM
●      2014-Up* GM
●      2019-Up* GM
