Removing CD Changer?

[PIKES]

hi, i removed my CD changer , as i do not use it; and to lose a little what.

But now i have no sound at all on the radio. ?

it's on boxster 05 , and a CDR 24 .

Does your car have the Bose sound package ? Its possible that by removing the Cd changer the MOST fibre optic loop is broken so the amplifier no longer communicates with the main head unit. Another possibility is you shorted out the wiring and the fuse for the radio went too.

Hi, thanks, yes it is the Bose Sound package.

can i re-loop 'some how' this Most fibre optic ?

The head unit lights still come on, But no sound at all.

Thought this may have been the case. The MOST loop is designed to connect each device in series and then terminate back at the head unit. By removing the CD changer you have broken the return link back to the head unit and to the next device (the Bose amplifier). There are termination adapters available to allow you to re make the ends from Male to Female plugs to suit the device you are connecting to, but you need to maintain polarity as each device has a twin connection (one in and one out). Possibly the simplest way to fix this problem is to get a single fibre optic cable and terminate both ends into a female plug , then attach this plug in place of the Cd changer to the now free end you have created. I beleive you can buy the fibre optic cable , plugs and adapters freely from either VW or someone like Dension (incar audio). The fibre optic is plastic strands but you do need to make sure its not kinked or crushed and the ends are not made dirty when you terminate them in the plug. The official Porsche route is to replace the current fibre optic cable with one suited for a bose only application , in truth its just a simple cable with a specific termination to allow the head unit to connect directly to the BOSE amp.

Yes that looks like the part , thanks Nick.. Not sure if it will also need a ink cable , best to find out. These are universal industry standard so do not need to be bought at Porsche , VW also use optical waveguide systems on newer cars such as the Audi A8 and Phaeton so the parts can be supplied from a local VW dealer here in the UK.
