I bought my wife a Pioneer SPH-10BT head unit to go in her 2009 Pop and was told that the standard ISO connector should just work, but it's not powering up the unit. Any ideas?

Been looking into it myself. If it had Blue & Me you need a adapter. Connects 2 do them

Popster, did you ever get tot he bottom of this? I have exactly the same head unit to fit to a 2014 Panda 1.2 easy. I have identified the aerial adaptor I will need, and the fascia adaptor plate, it is just the harness adaptor I am struggling with.

I have found one listed on ebay for a fiat 500, which I assume would be the same setup?

I don't have blue and me, or any other steering wheel controls or anything.

many thanks,

Lee
