Hi all.
New to this but looks like a fantastic factual site.

Looking to install a new single din aftermarket HU to my 2007 159.
Looking at getting a pioneer or kenwood bluetooth / Ipod compatible unit but was just wondering where can I get the ISO harness connector unit to wire up the new HU to the existing Alfa ISO blocks. Have looked at a few sites but none are listed as compatible for the 159 ??
Anyhelp much appreciated, and once purchased is it a case of simply plug and go or is there any other adaptation needed.

Thanks in advance.

whilst i've never seen the stereo connection on the 159, if it uses ISO connectors, then an adaptor harness should be no problem to source. the shape of the ISO plug is universal, and not peculiar to alfa or the 159. though the actual wiring pattern may differ slightly, but it is quite easy to cut-shut wires (ie: cut, solder, insulate) to create the right pattern.

i don't know what brands are available in the UK, but here in australia, Aerpro and DNA are 2 brands that offer wiring adaptor harnesses. as such, you can buy ISO-pioneer and ISO-kenwood without probs. these will ONLY cater for the power-ISO plug and speakerwire-ISO plug.

for steering wheel controls and any other accessories - that is, for the mini-ISO plugs - you will need additional, different adaptors. for example, you will need to buy an alfa-pioneer steering wheel control interface to retain SW controls; presuming the new headunit is compatible, and has the appropriate input (ie: you will need a model with 'Hardwired-remote Control Input'; not all pioneers have this).

you may need to visit an actual specialist ICE store (shock horror!), rather than try and shop online. find a pioneer retailer, and i'm sure they'll have the wiring adaptors.

You will need a fascia adapter as well, but in my opinion a double DIN unit would look better in the 159, although the fascia adapter is a lot more expensive (try ebay for this). I'm hoping to change my head unit soon and I'll be going the double din route for sure....
