iPhone 3gs can you use the iPod, gps (tomtom or navigon), and stream Bluetooth

I've googled this but have not found the answer.

Can A iPhone 3gs handle streaming music via Bluetooth, navigation (Tom tom in my setup), and phone calls (obviously the Bluetooth music would cut off) and then answer the phone call?

My current setup is my 3gs plays music through the car stereo's dock connector. I don't use Bluetooth for music and phone. The iPhone performs well with the Tom Tom software but I wonder if it can handle the bluetooh music stream.

And by not being able to handle I would define that as locking up or crashing and rebooting.

JAILBRAKE it and it will do whatever you want.

In want to know stock non jail break form since I don't want to run backgrounder. Just need to know prior to putting down money for a car stereo.
