Re: Need turn by turn navation on my windows 8.1 Htc phone
Windows Maps for Windows 10 will have that but I know its a ways off, just wanted to point that out before you spent a chunk of money on a navigation app.
I have a Nokia so I use Here Drive+ for free, but I think with an HTC you'd have to buy a license for it. I've also tried an app by Sygic, but I had bad experiences with it - app crashes and no GPS connection - the app has been updated since then so maybe it's better.
I've also heard people say that Navigon is good, but I've never used it.
