I'm currently using Bing maps only because it's on my Windows phone, however I'm very interested in Nokia maps on the new Windows Phone 8 phones. I like Google Maps as well.

Before I drive someplace faraway I'll normally use Mapquest and Google Maps. For me, Google Maps is great for when I need a street level look at the buildings or want a general map of the area. And Mapquest for the easy-to-scan icons for turning right or left or merging ect..

The cars have nav systems that I don't think use any of those listed.

Otherwise Google Maps on phone, tablet and PC.

Why? Gimme your address and I can see what you were doing in front of your house the last time Google did their street view drive-by (creepy ain't it?).

Google on my PC and Tablet. Bing on my phone, Windows 7 phone. So far the bing one on my phone has been pretty close to as good as Google for what I have used it for. Knock on wood.

Google maps

Google 9/10 times but at work I use Bing (it counts towards the reward points, and I'm a sucker for those and the free MS Points from it.)

google maps all the way. easy to use. would like to give igo a try but kind of expensive

Nokia maps. It is all offline, you get free updates every few months and it works extremely well.

Bling maps? Dont you mean Bing?

Google Maps and Local. Very feature rich and reliable navigation and syncs to my phone.

Google maps dog! The street view thing is pretty nifty as well.

Google Maps and Google Earth. And I have a TomTom in the Car.
Apple Maps apparently suck, there were streets renamed over 6 years ago which TomTom updated but Apple hasn't done it so far. Also, a complete neighborhood in my town is missing on Apples maps, but Tomtom got it :D
Kinda think theres a lot of work to do for apple!

Lol did know they are others online maps ^^
