  1. I have a 2004 996 carrera with an aircon problem. Basically the air coming out of the vents is cool but not cold. I thought this was down to the system needing re gassing so I had this done. The performance seemed to improve for a short time but is now under performing again. Also the AC compressor clutch seems to be engaging/disengaging every 15-20 seconds on tickover. Has anyone had a similar experience or can shed any light on this matter. Cheers Mike.
  2. Thanks for that. My car already had the main PCM unit so I bought the Nav drive and changer used. My local OPC confirmed that the DVD drive I bought would work so I ordered the rest of the parts and did the install. Pressing Main and Trip shows no coded devices so I guess its a trip to the Porsche dealers.
  3. I am in the process of retrofitting Nav and a CDC4 to my 997 carrera 2S. Eveything has gone according to plan but I'm a bit unsure about the optical connections. Does anyone know if the components need to be in a certain order within the loop. ie Nav first or CDC first. The optical waveguide allows you to connect either component first in the loop. Also am I right in thinking that once I have completed the install I will have to get an OPC to activate the components. Cheers Mike.
  4. I am in the process of retro fitting Navigation to my 2005 997 carrera 2S. I have all the parts and information I need after reading the TSB's on this site. However as an automotive engineer I decided to make the harnesses up myself, but I'm sturgging with the power connector that goes to the Navigation DVD drive. There are only three wires into the connector, +ve , -ve and a wake up wire. I know which pins are +ve and -ve but am unsure about the wake up connection. Can anyone help with wiring diagrams/pictures etc. I've had a look on the net but so far no luck.
