I recieved the head unit quickly and it was supplied with two connecting harnesses. Sadly neither one of these fit my car since I have a 2011 Mito with radionav and blue&me and this uses a quadlock connector. I purchased a quadlock connector and repinned it to the Isudar harness. From here on out everything worked fine but remember to setup the canbox in the radio, specifying which type you are using or else your steering wheel buttons won't work. Mine was supplied with a Fiat canbox adaptor and selecting a 2011 Bravo worked.
The unit works well however I experience once where the unit would not switch off when the car was switched off (I have read about this from other people) and Google maps crashed once. Also something to be aware off is the heat generated by the unit, I would make sure to keep all cables well clear when installing the unit. The easiest way to do this is to remove the Mito glove box as this will give you great access behind the head unit.
I had contact with Isudar regarding the repinning and they provided me with a simple pin layout since nothing is provided with the head unit. Communication was quick via the chat.
I will have to see how the device holds up in the next few months.
