Audi A1 upgrades, generation by generation.

The 8X from 2010 to 2018, mostly for rear parking sensors and for CarPlay, either a box behind the pop-up screen or an Android screen on Concert radio cars. GB owners come for activation of the smartphone interface, wireless adapters, dash cams and extended ambient lighting, because the car already has a touchscreen.

Yes. The box sits behind the dash and switches between the factory menus and CarPlay, so radio, navigation and the pop-up display work as before and the MMI knob and steering-wheel buttons control CarPlay too. Nothing is cut, and the car can go back to standard if you sell it.

It does. Speakers and subwoofers are wired into the factory amplifier, and an Android screen on the 8X is fitted with the adapter that keeps the Bose amplifier in play. On the GB the Bang & Olufsen system stays exactly as it is whether we add a subwoofer or upgrade the door speakers.

8X — 2010–2018 (three-door and Sportback): Concert or Chorus radio with a 6.5-inch pop-up screen, MMI navigation plus optional; no CarPlay from the factory. GB — 2018 on (Sportback and Citycarver): MMI radio plus with an 8.8-inch touchscreen or MMI navigation plus with 10.1 inches, MIB2+ hardware on most cars; Audi smartphone interface fitted to most cars, wired. Not sure? Send the reg on WhatsApp and we tell you the generation and the route.

CarPlay: A CarPlay box or an Android screen on the 8X; activation or a wireless adapter on the GB. Car radio: Android screen in place of the Concert radio and pop-up display on the 8X. Reversing camera: Camera on the box, Android screen or mirror on the 8X; coded into the MMI on the GB. Ambient lighting: Ambient LED kit on the 8X, extended ambient lighting on the GB. Parking sensors: Four rear sensors and a beeper that speeds up as you close in; nothing on the screen. Subwoofer: Under-seat woofer with a compact or DSP amplifier, no boot space lost. Dash cam: Hardwired from the driver's side fuse panel with a low-voltage cut-off. Speakers: Plug-in door speakers on both generations; Bose and Bang & Olufsen amplifiers stay. Soundproofing: Doors and floor treated with butyl and foam, trim refitted without marks.

CarPlay: under an hour for activation, two to four hours for a box or a screen. Car radio: two to three hours, usually the same day. Reversing camera: two to three hours. Ambient lighting: two to four hours. Most A1 owners wait at the workshop or drop the car in the morning and collect it the same day.

8X: the Concert or Chorus radio with a 6.5-inch pop-up screen, MMI navigation plus optional; no CarPlay from the factory stays and we add to it. GB: the MMI radio plus with an 8.8-inch touchscreen or MMI navigation plus with 10.1 inches, MIB2+ hardware on most cars; Audi smartphone interface fitted to most cars, wired stays and we add to it. Steering-wheel buttons, factory amplifiers and cameras are carried over on every route; the only route that changes what you see is an Android screen, and even then the controls are kept.

Send the reg or the year on WhatsApp or the form below and we confirm the generation, the route, the price and the next free slot. Every job carries a one-year warranty on the work, done at our workshop in Rosemount Business Park, Dublin 11, Monday to Saturday.
