Wiring leads / iso

With a Blaupunkt HU you don't need any wiring adapters. Depending on the year of your car you may need to wire in an ignition on feed. Around 2000 Audi stopped providing this feed (using the CANBUS to tell the HU whether the ignition is on). Either that or just use a scotchlok/piggyback onto the perm live and rely on turning the HU on/off manually.
You will need an antenna adapter:
