I need to build a navigation/routing application in 3D view like sygic, what are the available options if any?
Are there any existing open source or proprietary 3D mapping/libraries?
I have checked MapQuest, CloudMade and Openlayers2, but they don't seem to have this option.
Since some people have asked me what was the end result of this: I ended up writing my own framework with a friend that works cross-platform on iOS (iPhone and tablets) as well as Android devices.
Here is a link to a free basic Android TileCache viewer that I built with it

There is an experimental version that we did with elevation, elevation lighting and bathymetry (not in the released version yet).

It's been a while (i.e., years) since I've looked at this, but the last time I researched this the Bluetooth Serial Port Profile (SPP) was your best option. If there isn't any explicit documentation for an interface, you basically have to hope that the receiver outputs its data via the Bluetooth SPP, and that your Android device supports SPP.
There are known issues with this, though, depending on the receiver manufacturer and specific Android device. See the following:

There are some Android apps that claim to do this out-of-the-box:
...although I haven't personally tried them, and depending on your specific devices your mileage may vary.

We had similar requirements when looking for a Maps API for our OpenTripPlanner for Android open-source project, and we decided to go with Android Maps API v2.
Android Maps API v2 provides 3D camera control and 3D building renderings out-of-the-box, so you can easily create views like this:
Android Maps API v2 was feature/performance-wise far beyond the alternativies. If you prefer OpenStreetMap or other map tiles, you can load these via Android Maps API v2 as well.
The downside is that it requires the user to install Google Play Services on their device, but we found this an acceptable tradeoff.
OpenTripPlanner for Android is open-source, and we have 3D real-time navigation in our roadmap, but currently no one is working on this feature. If you'd like to use OpenTripPlanner for Android as a base for your application please feel free (licensed under Apache v2.0), and we'd definitely welcome any code contributions back to the project.
