996 Apple Play/Audio Upgrade from Porsche

I had one fitted a couple of months ago and very happy, the only slight issue was the fact it wasn't wireless which for the price is a bit poor BUT I picked up a dongle from cplay2air now wireless and even happier.

Oh totally transformed the car it now feels quit modern!

 
Hi

i just picked up a standard one I’m pretty sure there all the same,

updates arrive reasonably often.

 
Hello All

I've had the modified P.C.C.M. Plus unit fitted to my 2003 996 C2 for just over 2 months now. Unfortunately I'm now experiencing a problem with my Fuel Computer/Trip Reader on my dashboard. The problem is that periodically the fuel computer/trip reader keeps re setting itself to zero mid journey. Without me touching the fuel computer stalk or the instrument brinicle trip reader reset button. I wonder if anyone else is experiencing the same problem. The car has been back to my O.P.C. where it was fitted three times now. Without them being able to diagnose the fault. I must say they have been very understanding. However they say the P.C.C.M. Plus isn't linked to the instrument cluster in a way that could make the fuel computer/trip reader zero itself.

Whilst I'm on. Would I be right in saying that only cars that had a previously factory fitted P.C.M. 1 or 2 unit continue to get the secondary direction arrow/distance to junction display on the cars instrument cluster with a P.C.C.M. Plus unit fitted. My car had the single DIN CDR-22 CD Radio. I don't get the secondary information on my instrument cluster. I'm presuming this is correct and I won't ever be able to have the secondary information.

Lastly. Someone mentioned a dongle to be able to connect the mobile phone wirelessly. I presume this will work with an Android Phone.

Thanks Phil

 
I finally had mine fitted yesterday so will report back on operation in a few weeks. Only issue I ran in to ("only") is the recommended fitters (recommended by a great Porsche specialist near me) couldn't get the DAB reception to work very well. Said it might be a faulty DAB/FM splitter and I should speak to Porsche?? Anyone else run into any issues with the DAB reception on the PCCM+ unit? My car is a 2004 C4S with Bose.

To be honest I've never bothered with DAB before even in my modern cars I never use it, but it would be a shame to know it doesn't work properly on a brand new unit.

(I have the wireless dongle for Apple CarPlay on order from the states right now so will post about that here as well when it arrives).

 
I have a C4S installed the PCCM+ myself and have perfect DAB reception.

I think the issue you may have is the antenna amp. A lot of installers skip this step from what I've seen, either they don't have the original Porsche installation instruction which details what all the little bypass cables are for or they are just too lazy as the DAB will sort of work well enough for a demo without fitting the cables.

In the kit you have a few cables designed to be fitted to bypass the original antenna systems in the car and which ones you need depends on if your car originally had a CDR radio where it bypasses the factory antenna amplifier (found in the driver A pillar) or if you had a PCM where it bypasses the factory antenna amplifier and diversity module, since PCM equipped cars have two antenna's.

Additional risk of them doing this is you are feeding an already amplified antenna signal into another amplifier which can damage your radio circuit but hopefully that hasn't happed.

The reason you get bad DAB reception is because you factory antenna amplifier is designed to amplify FM and AM frequencies and attenuate everything else, which includes DAB frequencies. You essentially have a device blocking DAB on your antenna making it very had for your radio to derive a signal and the kit has the cable to bypass this device and the box that comes with the Radio is the new amplifier which separates and amplifies AM/FM and DAB.

So far I've seen so many of these installs bodged by people that claim to be professionals but just assume the kit will go in like any other aftermarket radio designed to work around a cars existing systems, but Porsche have had this designed to be essentially a factory replacement for the original radio and as such talking to the car on the CANbus and bypasses existing systems the car no longer need rather than working around them. Most aftermarket DAB radio's just make you install a second stick on antenna for DAB to your windshield but this modifies the existing antenna system to not need such methods.

 
Thanks for the super detailed answer! Really helpful. I will talk to the installers and find out what they did. Much appreciated. Will report back when I get to the bottom of it.

Hi, I’m not great with mk1 electrics cars and I’m sorry to say your OPC or at least in my experience have no clue if your car is more than 1 generation old but I may have some ideas.

First, there’s a few hidden menu’s on the PCCM, all can be obtained by going to your settings and holding the category for 10 seconds But you will need to check each one. You will want to disable anything CANbus related. I think a CDR22 has no CAN bus connector either way so this shouldn’t effect you only the PCM1 had it to sync the trip computer but easier to check without booking back in the OPC.

Second, in my mind more likely. Cars with MK2 electrics I.e had a CDR23 or PCM 2.0 can have navigation directions on the instrument cluster as the later cars have a completely redesigned instrument cluster with a dot matrix centre screen and a rare PCM 2.0 without the telephone function was available as a tequipment retrofit from the OPC so navi directions could be turned on to get directions on a CDR23 car retrofitted with a PCM2. However the guy who did your installation may have got confused and think a CDR22 and CD23 in a 996 must be basically the same thing so turn on the OBC to PCM communication setting on the computer like you would do on a CDR23 car so they get PCCM navigation which then has your car trying to sync its trip computer with a PCM1, of course the new radio doesn’t communicate with the trip computer and the OBC is put in an error state, resets and tried to establish communication again Which would explain your issue.

In regards to the wireless boxes, some are for CarPlay for iPhones, some for Android Auto for Android phones, you will need the correct box for the phone you are using.

 
Following the advice earlier in this thread I ordered a CPLAY2air which arrived today. Easily fitted and improves the convenience of the whole package. Would heartily recommend.

 
I am glad everyone is liking the wireless device it's a shame Porsche couldn't have thought of supplying one with the radio,

nothing more annoying than getting out the car walking somewhere and then realising the phones still in the car attached to its umbilical cord.

Merry Christmas and a happy new tier everyone!

 
The additional benefit of the CPLAY2 air is that it has allowed me to relocate the connection box so that it can’t be seen. I bought a new OEM cubby hole/ shelf and have put a wireless charger in it instead of the connection box. I bought an ANKER wireless charger as it was quite slim and also dark colour so blends in very well. Power runs off the CPLAY2air which has a power out USB slot. I connected a very short USB lead which now passes through a newly created hole on one side at the back of the cubby hole. The connection box is now hidden behind the cubby hole, and held in place with Velcro to stop it rattling. Ditto the CPLAY2air. The reason for the new cubby hole fitment is that I had cut a hole in the back of the previous one to allow the connection box to be pulled forward. See my earlier posts.

 
Good evening

I've just upgraded my 996C4 to a C4s Cab which has the original Unit with sat nav

I'm thinking of adding a Bluetooth adapter which I think will facilitate music and telephone access

or

Replacing with a new unit with carplay etc

Can anyoine recommend a good value unit if i go the latter route

Many thanks
