2011–2016 Chassis Codes: MD (5th Generation Sedan) | Model Years: 2011, 2012, 2013, 2014, 2015, and 2016
This page provides the complete 2011–2016 Hyundai Elantra radio wiring diagram for the fifth-generation MD sedan chassis. Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 2011, 2012, 2013, 2014, 2015, or 2016 Hyundai Elantra sedan.
The MD Elantra sedan introduced Hyundai’s “Fluidic Sculpture” design language and, for the first time on this nameplate, an available touchscreen infotainment display on top trims. Hyundai refreshed the sedan’s front and rear styling for the 2014 model year without changing the factory head unit connector. During this generation, Hyundai also reintroduced hatchback and coupe body styles under the Elantra name — the Elantra GT (UD chassis, built on the Hyundai i30 platform) arrived for 2013 and the two-door Elantra Coupe (J1 chassis, related to the Accent) arrived the same year. Both use different wiring than the MD sedan and are covered in their own dedicated guides; this page covers the four-door MD sedan only.

Frequently Asked Questions
What harness adapter fits a 2011–2016 Hyundai Elantra radio installation?
The MD-generation Elantra sedan uses a factory connector common to Hyundai vehicles of this era, and installers commonly pair this generation with the Metra 70-7304 Wire Harness Adapter, with a Metra 40-HD11 Antenna Adapter used where the factory antenna connector differs from the aftermarket radio’s standard plug. Confirm your trim’s exact configuration, since touchscreen-equipped models route some accessory wiring differently than base trims with a basic single-DIN receiver.
Does the 2014 refresh change the radio wiring on the MD Elantra?
The 2014 model year refresh updated the front and rear fascias, headlights, and taillights, but did not change the factory Head Unit connector or core audio wiring. A harness adapter that fits a 2011–2013 Elantra sedan will also fit a 2014–2016 model, so the wiring data on this page applies across the full range.
How do I install an aftermarket head unit in a touchscreen-equipped Elantra Limited?
Limited trims with the factory touchscreen navigation or audio display use the same underlying power, ground, and speaker wiring as non-touchscreen trims, so a standard harness adapter still applies. However, replacing a touchscreen unit typically requires a Dash Kit designed specifically for the touchscreen cutout, since the opening and surrounding trim differ in size from the base single-DIN radio bezel.
Does the 2011–2016 Hyundai Elantra have steering wheel audio controls?
Steering wheel-mounted audio controls became standard equipment across most Elantra sedan trims during this generation, including GLS and Limited models. A SWC retention interface is recommended when installing an Aftermarket Head Unit so the factory buttons continue to control volume, track, and mute functions correctly.
Is there a factory amplifier in a 2011–2016 Hyundai Elantra sedan?
No MD-generation Elantra sedan trim was offered with a factory Amplifier or branded premium audio system in the U.S. market; that upgrade was reserved for other Hyundai models during this era. All Elantra sedan trims drive the door speakers directly from the head unit, so no amplifier bypass harness is needed for a standard Aftermarket Head Unit installation.
