You have to tap the BT icon on the map in order to have the Turn By Turn go through the car audio
I must be doing something really stupid but I can't find the Bluetooth icon.
Still can't get the instructions over Bluetooth.

There is no bluetooth icon on the map?
On my 4S, turn-by-turn works over my Plantronics Voyager BT earpiece, but the first couple of seconds of each utterance is truncated.
Can it be done with the new maps?
That's odd :/
Phone call will work but the maps won't.
I even tried waze and that goes through Bluetooth but no luck with new maps.
iPhone 4 does not support turn-by-turn voice. No Siri. Only music and handfree telephone.I wonder if its something to do with iPhone 4 using 2.1 Bluetooth while 4s and 5 uses 4.0.
I just wanted to chime in with a possible solution. However, your phone must be jailbroken in order to take advantage of this fix.
First of all, I can confirm that the problem is indeed related your car's ability to switch from the mono hands-free headset profile to the stereo A2DP streaming profile. With my vehicle (Toyota Prius), the BT is always in hands-free mode by default. As such, any mono hand-free sound comes in automatically. To stream in stereo A2DP sound, my car requires me to manually change the input source to this type. Now it so happens that the iPhone uses the mono hands-free for Siri responses, but uses Stereo A2DP for navigation. Therefore, if I don't change my input source when navigating, I won't hear anything. Siri responses come in automatically though.
The solution for me was to install a jailbreak tweak called BTMono SBSettings. This tweak, when you turn it on, redirects all sound (including A2DP stereo) through the mono hands-free profile. So when the stereo navigation speaks, it now comes through the car audio automatically since it is coming in through the mono hands-free profile instead of A2DP stereo. In addition to this tweak, I also installed another tweak called SBProfile, which will automatically change the settings of my phone depending on certain triggers. For this issue, I set the trigger to be whenever the phone connects to my car's Bluetooth. When it does so, the phone automatically turns on the BTMono tweak, channeling all sound through the hands-free profile. When I leave the car (disconnecting the BT) it returns the setting as it was before.
Now, anytime I ask Siri for directions, the navigation streams in as it should. Problem solved!
