I sell the iPod Interfaces on ebay, and I'm constantly getting questions about whether they will work with many OEM receivers, including the ones in the Maserati.
I've talked to Blaupunkt technical support, and they say that NO aftermarket products work with OEM stereos. I recently had a customer successfully plug the iPod Interface into an Alfa Romeo 156.
I am developing a mod for the Blaupunkt disc changer, similar to what jbondox recommended, that will play the iPod. First version may not charge the iPod, but at least it will play. Another adapter mod I am working on will play and charge the iPod. The last version (later on) would allow the toggling back and forth between the CD changer and the iPod. I know some of you iPod lovers couldn't care less about using the CD changer ever again if you can get the iPod functioning.
If anyone is interested, please let me know.
