Hi motorers!
I've had the Aux cable for more than one year before finally switching to the iPod interface last Friday...
The installation was very easy with the MINI official instructions... I began to install it without the instructions and I didn't got far in the process before I finally gave my dealer a call to get those instructions. There are wires that need to be re-routed from radio wire plug to the iPod interface modul.
There is a huge improvement in both sound quality and use of the iPod. I have the MFSW and it is great! I didn't try the playlists function yet but it will only add to the pleasure of use!
I paid 198.50$ for the iPod interface and got it installed at a local shop. It took us 1.5 hour to install it but we lost a lot of time talking and fixing minor other things (remove Aux cable and old iPod setup, re-calibrate Boomerang). Installation was 40.00$...
So, for under 300.00$ (incl. taxes and installation), it is a very good upgrade from the Aux cable.
The only downside of it is that it doesn't display song tags on the radio display but I can live with that! I always plug my iPod in his dock when I get home. Then, when I have 5 minutes free, I quickly look at which songs played lately and I update the infos on those if needed...
BTW, I will re-install my Aux. cable soon because I paid for it and it is still great to plus a portable DVD player or a laptop...
