Mazda6 Infotainment by Year: TomTom, Gen 6, and CarPlay
The third-generation Mazda6 (GJ/GL, 2014-2021 in North America) had three distinct infotainment setups, and the year boundaries matter more than the trim sheet suggests. The 2016 boundary decides whether the car runs Gen 6 Mazda Connect at all; the 2018 boundary decides whether CarPlay came from the factory.
The short answer
Section titled “The short answer”| Years | System | Screen | CarPlay | Gen 6 / ScreenTune |
|---|---|---|---|---|
| 2014-2015 | TomTom-based unit, not Mazda Connect | 5.8-inch touch, physical buttons beside it | No, and no retrofit path | No |
| 2016-2017 | Gen 6 Mazda Connect | 7-inch touch + Commander knob | Retrofit only (USB hub + v70+ firmware) | Yes, on v74 |
| 2018-2021 | Gen 6 Mazda Connect, refreshed dash | 8-inch touch + Commander knob | Factory from late 2018, Touring and up | Yes, on v74 |
The Mazda6 left North America after 2021, so there is no Gen 7 Mazda6. Every used Mazda6 you’ll shop falls into one of these three rows.
2014-2015: a TomTom unit, not Mazda Connect
Section titled “2014-2015: a TomTom unit, not Mazda Connect”The earliest GJ cars do not run Mazda Connect at all. They use Mazda’s previous head unit: a 5.8-inch touchscreen flanked by physical buttons and knobs, with navigation supplied by TomTom. There is no Commander knob and no tiled Gen 6 home screen. Owner threads comparing the two systems confirm the units are not interchangeable; a dealer swap to Mazda Connect has been quoted around AU$3,000 in those threads, which is why nobody does it.
Practically, that means nothing in the Mazda Connect knowledge base applies to a 2014-2015 Mazda6: no Gen 6 firmware path, no CarPlay retrofit (the OEM kit requires a Gen 6 CMU), and no ScreenTune. If you want CarPlay in one of these cars, the realistic route is an aftermarket head unit.
2016-2017: Gen 6 arrives with the facelift
Section titled “2016-2017: Gen 6 arrives with the facelift”The 2016 refresh put the Gen 6 Mazda Connect CMU in the Mazda6: a 7-inch touchscreen high on the dash, the rotary Commander knob between the seats, and the same Visteon-built unit found in the ND MX-5, 2014-2018 Mazda3, CX-5, CX-3, and CX-9 of the era. Mazda’s service material groups the 2016-2021 Mazda6 with the rest of the Gen 6 fleet, so everything platform-wide (slow boot, the disclaimer screen, the parked-only touchscreen, ghost touch) behaves identically here.
These two years shipped without CarPlay or Android Auto. Both can be added with the OEM retrofit: a dual-port USB hub plus firmware v70.00.021A or later, the same kit used across the Gen 6 lineup. The Mazda6 CarPlay page covers the trim-removal specifics and the videos worth watching first.
2018-2021: the 8-inch screen and Mazda’s first factory CarPlay
Section titled “2018-2021: the 8-inch screen and Mazda’s first factory CarPlay”The 2018 model-year refresh kept the Gen 6 CMU but grew the display: an 8-inch touchscreen, standard on every trim including base Sport (2018 trim sheets). Touch still works only while parked; the Commander knob drives everything in motion, same as any Gen 6 car. The 8.8-inch non-touch widescreen you may have seen in a CX-5 or CX-9 was never offered on the Mazda6.
The 2018 Mazda6 was the first Mazda sold with factory CarPlay, and the rollout happened mid-year. Per Mazda’s own announcement, CarPlay and Android Auto became available in September 2018 as a no-cost dealer install for Touring trims and up; from November 2018, new builds at Touring and above came with it from the factory. Two carve-outs follow:
- Early-2018 builds (before the November cutover) need the dealer install or the standard retrofit.
- Sport trim never got it in any year, 2018 through 2021. A Sport is still Gen 6 and still retrofit-eligible.
All Gen 6 CarPlay is wired. Wireless on these cars means a third-party adapter; see the platform CarPlay timeline for the full lineup picture and CarPlay won’t connect when a working setup drops.
Which years ScreenTune covers
Section titled “Which years ScreenTune covers”ScreenTune targets the Gen 6 CMU on firmware v74.00.324A, which means the 2016-2021 Mazda6 qualifies and the 2014-2015 cars do not. The 2014-2015 TomTom unit is a different platform with no v74 to update to. For a 2016-2021 car, check the version under Settings > System > About (how to check); if it’s below v74.00.324A, getting to v74 is the prerequisite for ScreenTune and the recommended baseline for CarPlay regardless. Once there, ScreenTune handles the usual Gen 6 complaints: the every-drive disclaimer, the touchscreen lockout, boot time.
Identify your unit in ten seconds
Section titled “Identify your unit in ten seconds”- Buttons and knobs beside a 5.8-inch screen, no Commander knob: 2014-2015 TomTom unit. Not Gen 6.
- 7-inch screen, Commander knob, tiled home screen: 2016-2017 Gen 6.
- 8-inch screen, Commander knob: 2018-2021 Gen 6. Check Settings > Device for an Apple CarPlay entry to see whether the hub is already in.
