Dear all, Granted, this can be the umpteenth thread on endless discussion on whether can the USB/aux-in support can be added or not in the CD player only HU, which is supplied by Delphi on my 2012 punto dynamic. Today I actually got the HU opened at kashyap when they were repairng the broken AC vent, and on the top, it had a sticker which said-aux-R, aux-L etc and there was w white cuplar which was attached to the HU. On pressing CD button twice, it read "no source available". I need to know that what is that white cuplar's purpose, and second-can some type of aux-in supporting cable with jack/ cuplar be fitted on that HU and will it really support a digital music player? Also, can someone guide me that which store in Delhi/NCR can fit the aux-in jack, if any. OR is it worth going for kenwood KOS? will it support the KOS? I mentioned a specific point, hence a new thread.
