I have a Lumia 900 paired over Bluetooth with an RNS315 radio in a VW Golf. Music and calls play through car stereo as expected. Prior to the WP7 Tango update, while listening to music through Bluetooth, if a text message came through, the audio would silence and after a short pause, it would read the incoming text message through the car's speakers.
 
Problem: Ever since the "Tango" update, if a text message comes in while listening to music through Bluetooth, the audio pauses, but it does not read the text message aloud. Just silence.
 
I have removed the phone's Bluetooth profile from the car stereo (and car from phone) and connected the two. I have restarted the phone. "Read aloud incoming text messages" is set to "Bluetooth and handsets". "Enable speech recognition over the network" is checked. "Use speech when the phone is locked" is checked. None of these attempts has fixed the issue.
 
Again, this feature worked before the WP7 Tango update, but not after the update.

You are not the only one to report this issue so definitely a software bug:http://discussions.nokia.com/t5/Nokia-Lumia/Nokia-Drive-voice-instructions-SILENT-after-OS-update/m-...

Don't know whether this prior to software update but volume of spoken text reported very low here:http://forum.xda-developers.com/showthread.php?t=1850582

Just purchased a 920 to replace my 900... Had hopped that WP8 would have resolved the issue, but it doesn't work properly on WP8 either. Hope MS releases a fix!

I did notice that as one of the above links suggests, if I use wired headset, listening to MP3s, it seems to work as it should, but the volume is too low.

Also, not sure what happened, but when I get in my car and stream music over Bluetooth, the first text I receive after connecting will be read aloud, but any texts after that, the music just mutes for a few min then resumes.

Just as a matter of interest, which setting are you using here?

I had the same issue with my Lumia 822 in a VW Touareg, read a post to remove and reload the profile and that fixed the text replay issue.
