Re: Head Unit Help
If you dont want to use your steering wheel controls, you dont need an adaptor. You can just plug in the alfa ISO connectors.
You need only fascia adaptor and ISO mounting sleeve. You obviously need to install GPS antena and its cable to the HU to use the nvigation.
I am not sure if this is the rule with all 147 models, but when I installed my Blaupunkt Los Angeles HU I had to switch two cables in the ISO connector - permanent 12V and ignition switched 12V. On Alfa ISO connector they were reversed as Blaupunkt radio expected.
