Q:

I have a 2001 volvo v70 and I would like to add a cd changer to it or mp3 player please tell me how I could do that without changing my factory cd player.

A:

I just recently added 10 cd changer to my v70 and it wasn’t very difficult, all I did was run 8 pin cable from the cd player to the back of the car, I also run one wire to  number 10 fuse and added 10amp fuse and then I took it to the dealer to do software download which adds cd changer which cost $80, after do the software download the cd changer function shows when you switch in source button so then you are able to buy any adapter which plugs to the cd player and then to your ipod or any other mp3 player
