Requirement:
Porsche CR-1 and CR-2 radios
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 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) AUX input. 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 is available 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.

CR-1 and CR-2 radios do not require special removal tools, to remove:
1. Pry off plastic trim ring around the radio. (This exposes mounting points)

down and lock the radio into frame. (See Fig. 1)
