I’m posting this as I spent a lot of time of forums trying to see how to add a ‘MR12Volt’ Bluetooth adaptor to my 996 equipped with CDR23 and 6 CD auto-changer, and how difficult it would be. In short, I got there, and it’s pretty straightforward. Best resource to arrive at these instructions was a Youtube video from ‘Enfig’ (‘Porsche 911 (996) Bluetooth USB AUX Installation Dension’) (sorry not good at getting links). Different kit but similar install, and extremely helpful.
My spec - 2003 C2s cab with MOST fibre optic system, CDR23 and CDC-4 autochanger in the frunk.
I wanted to use my iPhone X for music streaming and bluetooth phone calls. I thought long and hard about the ‘double din’/heater relocate install of a fancy Pioneer/Apple Carplay/DAB system. But in the end I decided I wanted a stock look, and further to that liked the GT3 centre console delete mod. So I’ve done the console delete and installed a ‘MR12Volt’ Bluetooth adapter.
Console delete instructions are easy to find on the web and in the book ‘101 projects for your Porsche 911’.
So Bluetooth module install then:
1) I bought ‘Mr12volt’ adapter via eBay (Seller 023Jordan, Hong Kong supplier, fast service and well packed), and 2 positap connectors as I don’t trust wiretaps
2) Decided I would remove CDC-4 autochanger as I wasn’t going to use it any more
3) started in frunk. CDC-4 doesn’t need to be unbolted to pull it out as per some threads. It is held in place by two sprung clips attached to the bracket at the back. It you lift it up with a bit of wiggling it should come out of the clips/bracket. Might help to pull the bonnet seal away, I did which made it easier.
4) MOST cable easy to pull off by pressing clip on connector. I attached the MOST looper from the Bluetooth kit by simply plugging it into the pulled off connector. Pushed wires behind amp.
5) Wiring connector harder to get off, needs a small screwdriver down the front of the connector to release the clip. Take care, a bit fiddly and if like me you want the option to replace the CDC-4 in future you need to not wreck the connector or the CDC-4. Not too tricky if you are patient and gentle
6) Taped up the wiring connector and again pushed behind the amp
7) Removed amp bracket with 10mm ratchet spanner to leave a tidy bay. Two bolts. Replaced bolts, and put Velcro backed tool kit in place where the CDC-4 had been, looks like it was meant to live there
8) Into car, turned CDR23 on, ’CDC’ option not available, suggesting the MOST looper was doing it’s job
9) Removed CDR-23 using Becker ‘keys’ bought from eBay for 2 quid. Once CDR23 is out the ‘keys‘ release by pressing a flat blade screwdriver into blue spring clips on side and wiggling ‘key’ out
10) Disconnected plugs on back of CDR23, easy peasy by pressing clips. Took a photo beforehand just to make sure I remembered where to put them back in!
11) Wired power cable for MR12VOLT by posi-tapping in as per the ’Enfig’ video referred to above, then plugged power socket into MR12VOLT
12) my MR12V kit came with a female MOST connector and 2 males in a loop. Plug female into original CDR23 MOST feed cable and plug new males into back of CD-R-23 and MR12VOLT
13) Set dip switch on MR12V to ‘3-on’, all others off
14) Routed iPhone Lightning cable (for charging) and mic cable around the centre ‘horseshoe’. Horseshoe comes off easy if you follow the steps in the Enfig video and use the right trim removers. Mic placed behind steering wheel not far from intermittent wiper rheostat. Again, take time and care so as not to damage any clips. Plugged both into MR12VOLT
15) Used 3m double side stickers supplied with kit to stick MR12V to back of the void where CD-R-23 goes. Plenty of space in my car
16) pushed cables to back of void carefully to avoid crimping them when pushing the unit back in
17) pushed CDR23 back in. Turned it on. Cycled to ’CDC’ which was now available again. Paired ‘phone as per instructions. Music, phone working. Bingo! Smug looks all round.
Sounds pretty good, low noise, even works with Siri. Really pleased. Total cost of mods approx £300 including centre console delete.
Chuffed to bits that it all went well, simple really, and end result is great, and so much better looking and much cheaper than double din route (in my humble opinion!).
Hope that helps any who are scratching around for support like I was. Thanks again to ‘Enfig’ for their vid, really helped.
