Overview
The Kenwood DMX400S is a 6.8 inch double DIN digital multimedia receiver with wired Apple CarPlay and Android Auto, built-in Bluetooth and a rear camera input. It suits drivers replacing an aging double DIN stereo who want smartphone integration without paying for a built-in navigation unit.
This is a digital multimedia receiver rather than a traditional radio deck: there is no CD mechanism, and the screen is the primary interface for CarPlay, Android Auto and USB mirroring on Android phones. The 13-band EQ and digital time alignment give more sound-tuning control than most stock head units, and the shallow-mount chassis is aimed at fitting into more dash openings than deeper aftermarket decks.
- 6.8 inch capacitive touchscreen, double DIN
- Wired Apple CarPlay and Android Auto
- Built-in Bluetooth for calls and audio
- 13-band graphic EQ with digital time alignment
Who it's for
Good for owners of vehicles with a double DIN opening who want wired CarPlay or Android Auto and a rear camera input on one screen. Not for anyone who specifically wants wireless phone connection, since this model leans on a USB cable.
Pros and cons
- Double DIN with a large 6.8 inch capacitive touchscreen
- 13-band EQ and time alignment for real sound tuning
- Rear camera input included
- Shallow chassis eases fitment in tight dash openings
- CarPlay and Android Auto are wired, not wireless
- No listed built-in navigation
Performance notes
The shallow-mount chassis is meant to ease installation in vehicles where behind-dash depth is limited, and the 13-band graphic EQ plus digital time alignment give an installer more room to correct for speaker placement than a basic head unit's bass, mid and treble knobs. CarPlay and Android Auto both run over a wired USB connection rather than wirelessly, and Android phones also get a USB mirroring mode for apps beyond Android Auto's own interface.
