Introduction
If looking to add Bluetooth® features to Porsche CR-1 or CR-2 radios you should
consider the A2DIY-CR12adapter kit. This revised easy to install kit is essential to
adding Bluetooth® features to older Porsche vehicles while keeping everything
stock. This “triple play” module supports aptX "CD-like’ high quality audio for
streaming music and 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 without changer. Use included media remote
control to adjust Smartphone: volume, track up/down/pause and more and can be
mounted to steering wheel or dashboard. In addition, an optional “Smart charger’
kit helps to keep devices charged while on the road. Thanks to the A2DIY-CR12 kit,
Porsche owners can update to Bluetooth® without changing original radio.
Warning: Porsche CR-1 and CR-2 radios are coded and will not operate without
the code. Do not proceed with step 7 if radio code is unavailable otherwise radio
will not operate upon reconnection.
See Frequently Asked question at the end of this guide for more details.
