This weekend I added an auxiliary cable to my base model TDV6 so that I could connect my iPod to the stereo. I found the method on another forum, and I have to say that it's very easy and the sound quality is superb. Basically, you remove the plastic trim from around the bonnet release catch in the passenger foot well. There you will find 3 connection blocks, the middle of which (light grey) has three wires which terminate there (the black one is a ground for shielding, the blue one and the red one are the stereo connections for the AUX on the stereo). On the higher models these go somewhere, but on the base model they stop here. Cut them at the point where the enter the block.
In the top of the upper glove box there is a small slit (there's also one right at the back but you can't use that one). Get a 3.5mm stereo cable which can plug into your iPod and cut the connector off one end of it. Feed the cut end through the slit and with a few tries you should find that after lowering the lower glovebox (to access the fuse board) you can grab the cable, feed it down to the cut AUX wires and either solder or crimp connect them toghether. Make sure you connect the ground shielding of the new cable to black, and the left and right to the blue and red wires. Refit the trim, plug the cable in the glovbox into your iPod and set the volume quite loud on it and press AUX on the stereo. Volume can be controlled on the stereo as usual. :D
One of the really nice things about this method is that the cable is completely out of sight inside the glovebox.
