This thread started on January 6th and my post dating back to January 7th clearly mentions that USB or AUX can not be added to any car manufactured June 2010 onwards because all FIAT cars manufactured June 2010 onwards come with non Blaupunkt/Delphi head units. Blaupunkt Head Units have Blaupunkt written over them like in the pic below. I am surprised that more than 2.5 months later, this same thread is having same queries. No offence. Link to previous post dated 07th January 2014 http://www.teamfiat.co.in/car-enter...rt-punto-dynamic-2013-model-2.html#post210659 @Pra.agar- Changing the HU does not void warranty as long as no wire is cut. I am planning to change the HU soon as well and get some pioneer 1-din HU with Bluetooth+USB+AUX support. Only thing is that it is so hard to let go of the stock look of the Fiat's OEM Delphi HU.
