Gonna got a Sony head unit to my c8. Doesn't look too hard, will lose the menu options that you can select with the standard unit, but there's nothing there that I need. Ordered a harness that includes the aerial adaptor. I'd appreciate any advice, but mainly I'd like to know if it's easy to access the top of the dash where the time and radio display is as I want to run a microphone cable through to the top of the steering column, and also how to drop the globe box, so want to run a dab aerial through to the window?? I'm installing in a couple of days, so any advice would be great. Thank you
