- Series 2 IQ conversion. Requires a Tech 2 and possibly a modded HVAC module. Also may need a reverse camera module. You also get a tiny-ass screen. I'd recommend going through Envyous Customs for this.
- Aerpro 2DIN Fascia kit. This allows you to use any head unit you wish, offers the highest audio quality and offers the option to convert single-zone HVAC to climate control. Only works with single zone cars, and will still need a Tech 2 if you plan on swapping your dual zone to single zone CC.
- Android Head Unit. You'll need to go with the Kayhan or Dig Options "Tesla Style" unit as the standard one is for single zone CC only. You lose tacticle HVAC controls, which is a massive pain imho. You'll also need to go with an aftermarket amp, as they tend to skimp on amp quality for these chinese units.
I went with option 3, in the tactile controlled single zone version and I couldn't be happier. I use a compact Sony 4ch amp over RCA and then wired that into the stock wiring harness. Added a pair of Pioneer under-floor subs too, and with the option to add Android Auto/Apple CarPlay via Headunit reloaded or a multitude of other apps, you're laughing.
