hi was looking for help im trying to put a alpine (ixe-W400E) double din head unit in my 2012 polo and was wondering if there was anyway to plug it in without spending $150 on a steering wheel control wiring harness i dont care about having steering control i have found a adapter that goes straight from the factory plug to iso but i was wondering if there will be any issues
