Step 3 - plug the other end of the data cable into the Grom interface which is small enough to leave behind the stereo or ideally route into the glove box.
Step 4 - connect your chosen accessory cables and route to your preferred location around the drivers seat.
Step 5 - Install head unit and enjoy!
