I know there are several threads on this forum already about changing the Evo factory radio. I have read most of them but I have a few questions I would still like to ask. The radio has to go, I really dont like the system. So I have found a glossy black fascia replacement on ebay. I am going to fit a single din unit with a motorised flip display. I realise it will cover up the hazard button and possibly the top vents but I can live with that. I also dont care about losing the bluetooth and phone features. However I would still like to use the USB and AUX inputs next to the gearstick.Is this possible without major rewiring? I don't want to be cutting any cables I just want a straightforward iso connector fitting just in case I want to put the OE back in. My last question is can I expect the volume and mute buttons on the steering to still work?
