Mazda CX-5 Infotainment Overview
The CX-5 ran the Gen 6 Mazda Connect system from the 2016 facelift through the 2020 model year. The 2013–2015 first-gen KE used an older TomTom-based head unit, and the 2021 redesign moved to Gen 7; neither shares the CMU this site covers. Everything below is CX-5-specific. For anything that applies to every Mazda Connect car (boot behavior, CarPlay troubleshooting, firmware, ghost touch), follow the links into the platform knowledge base rather than re-reading it here.
Model years and what’s inside
Section titled “Model years and what’s inside”| CX-5 | Years | Head unit | Screen |
|---|---|---|---|
| KE, 1st gen | 2013–2015 | TomTom-based, not Mazda Connect | 5.8-inch |
| KE facelift | 2016 | Gen 6 Mazda Connect | 7-inch touch |
| KF, 2nd gen | 2017–2020 | Gen 6 Mazda Connect | 7-inch touch; 8-inch touch on 2020 GTR/Signature |
| KF redesign (NA) | 2021+ | Gen 7 | 10.25-inch non-touch |
Nearly every KF runs the 7-inch touchscreen; the 2020 Grand Touring Reserve and Signature got a wider 8-inch touchscreen on the same CMU. Both are touch panels, so the touchscreen-while-driving lock applies to both.
The 2021 redesign is a different system end to end. See Gen 6 vs Gen 7 for why, and the 2021+ CX-5 infotainment notes for what changed.
CarPlay arrived for 2019 on Touring and up; earlier cars retrofit it
Section titled “CarPlay arrived for 2019 on Touring and up; earlier cars retrofit it”Factory CarPlay was not available on 2016–2018 cars. Mazda released a retrofit kit in August 2018 (a dealer-installed USB hub plus a firmware update) that brings wired CarPlay and Android Auto to those cars. For 2019 and 2020 it shipped from the factory on Touring and up; the Sport still took the retrofit.
So if you have a 2016–2018 CX-5 with no CarPlay, that’s expected, and it’s fixable. The full breakdown of the retrofit kit, part numbers, and the DIY-vs-dealer question lives on the CX-5 CarPlay page, with the platform-wide version at CarPlay retrofit.
CX-5-specific quirks
Section titled “CX-5-specific quirks”- Ghost touch on 7-inch cars. Phantom inputs and the screen registering presses you didn’t make are a known touch-panel hardware issue, not software, and documented failures cluster on the 7-inch digitizer. See CX-5 ghost touch and the platform mechanism writeup at ghost touch.
- Black screen, reboots, no audio. On the CX-5 this is frequently downstream of low battery voltage rather than the CMU itself: a weak or aging battery browns out the head unit. See black screen / reboots / no audio and battery drain and low voltage.
- Navigation SD card. Nav-equipped cars use a Mazda-specific SD card; aftermarket or wrong-region cards won’t load. See navigation SD card.
Update the firmware before troubleshooting anything else
Section titled “Update the firmware before troubleshooting anything else”Bring a Gen 6 CX-5 up to current firmware before chasing other faults; many “broken CMU” reports are just old software. Check yours at Settings > System > About. The CX-5-specific version notes are on the CX-5 firmware page; the procedure and version history are shared at firmware versions and how firmware updates work.
The supported-software target for these cars is v74.00.324A. If you’re tuning the Gen 6 system, ScreenTune is built for the CX-5 on that version; check supported vehicles before buying.
