Atwell, you can listen - if you can hear it! Doesn't always work so well in a topless Lotus.
It also gets funky if you're playing audio from the phone, and a little bit of spoken navigation goes a long way; I don't need constant chatter. I usually have the sound turned all the way off whether using factory nav, TomTom, mobile device, whatever. The Android Wear functionality is really cool because you can get a vibration when you're coming up to a turn. I also want to be able to look at a glance to see how long before the next turn; the voice alerts generally won't do that except at specific intervals.
The Waze crashing is really annoying. I actually haven't really used it at all with my latest phone, but on my last phone - a Nexus 6, so a close to pure Android as you can get - it would just randomly shut down sometimes on long trips. Older versions would have weird crashes. No problems whatsoever with Google Maps on any of my devices; the fact that Waze is Google-owned makes it especially galling. The login is screwy too; I have an actual account with a username and all that works on the web, but often the mobile will only let me log in with the phone number... it's just not all that refined. I do like that it has speed and speed limits; both missing on Google Maps.
I've occasionally tried Nokia's "Here" a few times, too, but that really is a bug-filled mess last I tried; it often won't even open.
I've hemmed and hawed about getting a modern radar detector and my conclusion in the past few years is that it's just not worth it, even the best just isn't good enough - nothing is a license to speed. Nor should it be! I have trained myself pretty well to very rarely go more than 10 over the limit and haven't gotten pulled over in years, and I always try to live by the axiom, "don't drive like a dick" - in other words, I don't do things that'd piss me off if someone else did them to me - go do a track day if you want to really drive fast. The "blind spot monitoring" problem with radar detectors is a real one, too, and probably insurmountable.
Anyway, a really good radar detector is $400-500 and there's no guarantee you won't get a speeding ticket - you can just drive reasonably carefully and you can even rack up a ticket or two for less than the radar detector will cost.
Back on topic - I don't have a Ford, but I've played a little with the Sync in my parent's Escape, and to call it clunky is a compliment - without spending real time on it, it looks to me like a really bizarre system. But then, the system in my wife's Mini is wacky, too, so maybe it's an industry-wide syndrome.
