A2DIY-CR12
QUICK START BLUETOOTH INSTALLATION GUIDE FOR PORSCHE CR-1 AND CR-2 RADIOS
Created January 16, 2016
Revised September 23, 2020

Introduction:
If looking to add Bluetooth® features to Porsche CR-1 or CR-2 radios you should
consider the A2DIY-CR12 kit. This revised easy to install kit is essential to adding
Bluetooth® features to older vehicles while keeping everything stock. This “triple
play” module sounds great for (1) mobile conversations, (2) streaming Pandora,
Sirius radio, Apple music, audiobook, podcast and (3) CD changer retention or an
AUX input (for vehicles with changer). Use included smart remote to adjust
Smartphone: volume, track up/down/pause and more and can be mounted to
steering wheel or dashboard. In addition, an optional “Fast charge’ USB port helps
to keep devices charged while on the road. Thanks to the A2DIY-CR12 kit, Porsche
owners can update to Bluetooth® 4.1 without changing original radio.
Works in vehicles with or without CD changer.
If retaining CD changer; skip to installation 2 on page 4.
See Frequently Asked question at the end of this guide for more details.
