So I bit the bullet today and offered an 8" Android head unit. Looks pretty nice, hopefully it does what I want. I want Waze in my dash, which this will definitely do. I will set up a tasker profile so my hotspot turns on as soon as the Bluetooth connects, so I will always have data available. Beyond that, the stock head unit pisses me off when listening to audiobooks. It has a "gentle fade" when listening over Bluetooth, presumably to avoid loud jolts as you go from total quiet to sound. That works fine for music, as there isn't typically a long enough quiet pause to trigger that fade in. But with audiobooks, it is always clipping off the first word or two of sentences after a slight pause. Gets really damn annoying. Doesn't do it through the aux in, but I don't want to plug in my phone all the time, and that defeats the whole Bluetooth calling thing. So if I get waze and happy audiobook time, Brad happy.
Torque Pro and Google play music in the dash is a bonus.
Got the Joying JY-VQ122, direct from the manufacturer for a little less than 400.
I will post pics when it comes...
