Thanks for all the helpful opinions. What does "depth of integration" involve?
4 examples come to mind:
-Using google voice search command "Navigate To _____" to enter in a destination, without opening the program and typing everything in. BTW, there is a huge convenience in doing this not only because of the ease of destination entry, but also the ease of opening google voice search (just hold down the spyglass/search button on your phone for 2secs).
-Browsing the internet on your phone, then seeing an address (in google maps, or even on a web site!) that you want to go to. Then you just hold your finger down on the address and it will give you the option to open it in navigation and take you there! With Sprint nav, you must write down the address on a piece of paper, open sprint nav, then type the address back in.
-The ability to open up your contact list and merely touch the previously entered address of a contact... which then opens Google Nav and takes you there!
-The ability to flip back and forth, in your phone, between google maps and google nav. You can search for whatever you like in google maps (extremely helpful for searching topographically when you do not know the exact address), and then flip over into google nav to take your there.
We just took two trips to california over the last 6 weeks. We had the opportunity to test both out several times and google maps won us over. Especially when it came to side streets -the sprint nav became a major disaster.
Once I was using Sprint nav on a 2-lane road. I was in a hurry and I hit some really heavily backed-up traffic. I got Sprint nav to go into detour mode in an attempt to get around the traffic. It instructed me take the next left, then the next right... and then it drove me straight into a dead end. No, it did not make a mistake thinking that it wasn't a dead end, it showed a dead end on the map! While I was approaching the dead end (I could see it coming) it instructed me to make a U-turn... then navigated me back to the road that I had come from. I had wasted a bunch of time and was stuck trying to make a left back into the heavily backed-up traffic.
After that bad incident with Sprint nav (granted, it seems to have been a very unusual occurrence) I have avoided using it ever since.
