I’ve searched around a bit and I have found several posts about adding a nav unit in, but I haven’t seen anyone replacing the nav in their 2012. Really I just want to get a whole new HU(nav isn’t needed really but need Bluetooth since my phone doesn’t have an auxiliary port for music) but if it has nav that’s a plus. My biggest thing is I’m not car savvy and barely tech savvy. I know enough about both to make it by, but I don’t know what to do for this instance. I know Best Buy usually jacks prices up, but is it my best bet to take it to someone and have it done. And also what Unit does anyone recommend? Thanks!
