I am adding (or attempting) the Compass module to my 2006 CTT. I got the module and bracket, but do not know where this installs. I remember reading this was under the back seat, but that does not seem obvious from a brief inspection.

Any ideas?

 

i'd say it sits at the top of that unit. that small rectangular housing looks like it holds the magnetic field sensor. now to locate the wiring

pre 05 models used that additonal bracket you have and clips into the seatbelt receptacle

i have an 04 model and i'll be doing the retroift too, but only if i can locate the harness. my option code is QR0 which is without compass. QR1 is with compass. i've heard that all cayennes fitted with PCM/NAV have that harness, but i can't confirm that.

 

The wiring is the problem alright - I could not locate it. I have PCM/NAV but no compass connection...

 

i think you're right. i've looked at several 04 cayennes with pcm/nav. i haven't been able to locate that harness for the compass module. looks like pcm 2.1 maybe the way to go or build a harness

 

Mine is an '06 so I have the DVD based PCM. That does not seem to be helping. I think it is time to build a harness, the audio unit next to the mount might provide all the connections needed:

 

oh ok.....there's software to enable compass in the cluster.

Funny, it says part # 955 044 900 28 is for '05 and above, but when you order it states this is for the '08-11 Cayenne. That is PCM 3.0. I wonder how I can get the proper connector for this Compass module? I knew that dealer programming was going to be required, I figured to piggy back this with the trailer hitch upgrade I am doing.

 

hmmm.....thats weird because everywhere i've looked. it clearly states its for pcm 2.1 for dvd only. i could look into it at my end and ask our parts guy

 

Thanks!

 

ok.....just spoke with our parts manager. that software shown works from cayenne 03-11 and is compatible with both pcm 2.1 & 3.0. hope this helps

 

What exactly does the compass module give you? Is it for the nav system display? I have an 04 CTT, is this upgradeable as well?

 

the compass module on pre dvd nav models gives you the N,E,S,W increments on the left hand side of the display on the cluster. to get compass on the pcm screen (pcm 2.0), you need the extended nav update

 

Thanks, I have the indicator to the left side of my cluster already, what is the extended nav update? How does one tell what version of PCM they have?

 

if you have pcm 2.0 you have nav which works via cd. pcm 2.1 works via dvd and has a seperate player which sits under the passenger seat. pcm 2.0 vehicles have a storage drawer under the seat. here's the link to explain extended nav. its enabled via the dealer using the piwis tester. software is @ $200

I have a 2005 CTT with 2.1 PCM with DVD. I did not have the compass on the left hand side of speedo. I upgraded to a new pcm with the phone buttons, as my old one did not have them, and I wanted to get mobridge.
WHen I got my new to me, used PCM and hooked it up ... the compass was there on the dash. I think the new pcm had the programing.
