The fibre optic system only connects the individual units
I have no idea what stereo you have fitted to your vehicle, perhaps a foto may assist.
Try removing your stereo, pulling the MOST (fibre optic cable usually orange) and with the ignition on see if there is a red light shining thru the cables.
Next try the most cable at the amp and so on, again I dont know what else you have fitted SAT nav is usually on the MOST loop

not sure how to and also was told the amp was changed just before i brought it but yes still could be the amp i supose
ok i will strip it out and see whats going on i did check in the boot left had side and like i posted area tried the hands free bypass which worked for around 16 seconds then everything powered down. i seems like the red light thats shines from the MOST only stays on for a little while then powers down and no red light then so im guessing thats stops the comunication.

ok watched the video and the problem i have is that no matter what module i put the fibre optic cable in. it wont pass on the light to the next module like shown in the video? surely they cant all be snookered ? i used the loop tool just to comfirm that it was not the fibre optic cable its self and it passes thre light to the next plug on the loom fine ?

Sheesh, sorry for your troubles matey, that must be really frustrating.
If things are that complex and fragile I am glad my old P38 doesn't have it (it's got enough problems of its own anyway).
