Sorry to wake this thread up again. I have an issue while using Sygic and playing audio at the same time where the phone becomes totally unresponsive and the only way to fix that is to take the battery out and and restart the phone. I know Kamikaze reported a similar problem but I haven't seen any solution to that, so was wondering if anyone knows how to fix it.

Steps to reproduce problem are:

1. Connect N900 to the car charger
2. Turn on Media Player or Vagalume (tried with both local and streaming audio) and start playing something there
3. Turn on FM transmitter and FM Boost
4. Turn on Sygic
5. Creat a route to any destination
6. Start driving the car. Audio keeps playing and Sygic gives directions for may be a minute or so
7. After that everything simply freezes. It is reproducible every time.
8. The problem doesn't occur if only sygic is on with FM transmitter or if only media player is on with FM transmitter.

So has anyone encountered the same issue? If so, is there a solution to the problem?
