Jaguar Audio Connectivity Module (ACM): what it is and the modern alternative

A wired input for an iPod, a USB stick or a music player

• A dealer accessory for the X-Type (from 2002), S-Type (from 2003) and XJ (X350/X358, from 2004). The XK (X150) had its own version.
• It adds a pair of RCA audio inputs, a USB port and an iPod cable, usually in the centre armrest.
• It connects to the radio through the CD changer input, so the music plays as the CD changer source, controlled from the radio and the steering wheel.

Look inside the centre armrest

If there's a USB port and a pair of RCA sockets or an iPod lead in the armrest storage, your car most likely has the ACM. If the armrest is empty, it doesn't — the ACM was an accessory, not standard equipment.

It's wired, and it's built for the iPods of its time

• Everything is by cable: no Bluetooth, no streaming from apps like Spotify unless you plug the phone into the RCA inputs.
• The iPod connection uses the old 30-pin connector of the 2000s.
• It was a dealer part costing several hundred dollars, plus fitting.

Bluetooth through the original radio

For the X-Type, S-Type and XJ, the JAGAUX Bluetooth adapter streams any app from your phone through the factory radio, with track control from the steering wheel and hands-free calls. It also has an AUX input for a cable if you want one. It plugs in behind the radio — installation guide.

XK / XKR (X150): you don't need an ACM to play your own music — the AUX input can be activated: AUX activation in the XK.
