gps inaccurate iPhone 4

After opgrading to iOS5.1 it suddenly seems like med GPS has become very inaccurate. I have been using sygic as my GPS software without any problems for a long time, but suddenly both the pre-installed map on my phone and sygic show my position as inaccurate and far away from my actual position. Any suggestions?

No sound from application sygic when using Bluetooth iPhone 3G

I have a Viseeo bluetooth device to enable my iPhone to use the cars phone interface (steering wheel controls, microphone, radio etc). This works well with the iPhones phone features. However, when Bluetooth is enabled I receive no sound from my navigation program (sygic Mobile Maps AU/NZ) either from the iPhone speaker or over the cars sound system.Ive been in contact with sygic and they tell me:Apple wont allow applications other than phone and iPod to send audio over bluetooth, and thatThey are unable to specify that output should go via the iPhones speaker. If Bluetooth is on then all (allowed) audio is sent over Bluetooth. All other audio is simply lost.Does this match your experience, or are there exceptions? It seems a shame to have to disable Bluetooth (and with it, handsfree phone) just to be able to hear voice directions from the GPS.David 3GS OS 3.1 iPhone OS 3.0.1
