Audi TT upgrades, generation by generation.

The 8J from 2006 to 2014, nearly always for the Android screen in the double-DIN slot, because the Concert radio has no display to work with. 8S owners come for CarPlay activation on the Virtual Cockpit and for a wireless adapter, and 8N owners for a single-DIN unit and a speaker upgrade.

Yes. On the 8N and 8J the Android screen is fitted with the adapter that keeps the Bose amplifier and its subwoofer working, and new door speakers are wired into the same amplifier. On the 8S the Bang & Olufsen system stays untouched whether we add a subwoofer or upgrade the speakers.

A little. The roadster has less boot and no rear shelf, so the subwoofer is a small under-seat woofer rather than a boot enclosure. The reversing camera sits above the number plate on both bodies, and on the 8S it is coded into the MMI so it shows on the Virtual Cockpit like a factory one.

8N — 1998–2006 (coupé and roadster): Concert or Chorus cassette or CD radio in a single-DIN slot, no screen; Bose optional. 8J — 2006–2014 (coupé and roadster): Concert or Symphony radio in a double-DIN slot, RNS-E navigation optional; Bose optional; no CarPlay from the factory. 8S — 2014–2023 (coupé and roadster): Virtual Cockpit only, no centre screen, MMI on MIB2 throughout; Audi smartphone interface optional from around 2016, activation possible on most cars; Bang & Olufsen optional. Not sure? Send the reg on WhatsApp and we tell you the generation and the route.

CarPlay: Activation on the 8S Virtual Cockpit, an Android screen on the 8J and 8N. Car radio: Android screen in the 8J's double-DIN slot, a single-DIN unit with a floating display on the 8N. Reversing camera: Camera coded into the Virtual Cockpit on the 8S, on the Android screen on the 8J and 8N. Speakers: Plug-in door speakers on every generation; Bose and Bang & Olufsen stay. Subwoofer: Slim enclosure in the coupé boot, under-seat woofer in the roadster, DSP amplifier on the factory signal. Ambient lighting: Ambient LED kits on the 8N and 8J, extended ambient lighting on the 8S. Parking sensors: Four sensors in the rear bumper with a buzzer that beeps faster; sound only. Dash cam: Hardwired from the fuse box with parking mode and a low-voltage cut-off, cables hidden. 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. Speakers: two to four hours depending on how many speakers are changed. Most TT owners wait at the workshop or drop the car in the morning and collect it the same day.

8N: the Concert or Chorus cassette or CD radio in a single-DIN slot, no screen; Bose optional stays and we add to it. 8J: the Concert or Symphony radio in a double-DIN slot, RNS-E navigation optional; Bose optional; no CarPlay from the factory stays and we add to it. 8S: the Virtual Cockpit only, no centre screen, MMI on MIB2 throughout; Audi smartphone interface optional from around 2016, activation possible on most cars; Bang & Olufsen optional 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.
