I found the kits from 4dtech and infotainment but $1500 is an awful lot to throw down, does anyone else know where I might be able to find one cheaper? I saw that Tesla one but it looks as if I’d have to buy too many add ons to get the same functionality ie you’d have to purchase steering wheel adapter, sat radio cable and apple/android dongle that doesn’t even neatly install so you’re already back up over $1000 by that point.
