Google Maps iPhone with Leon Bluetooth

[Rampage]

Has anyone had a problem with using the new Google Maps iPhone app with the Bluetooth in a Leon?
Whenever I use the navigation on mine the phone constantly tries to ring itself (ring my own number). It only does it in the car, and turning the Bluetooth off stops it happening!
Any ideas?

It dials your number so it can play the directions through your car speakers (Siri does the same), which it does but it takes so long to do this that by the time you hear the prompt you've already gone past the turning. I just stick with the Apple Maps app which plays through the phone.

Google maps plays through my Pioneer bluetooth stereo and its a cool feature, looks like a call on the headunit but only says directions and then goes back to the music

I hadn't realised that's how it works.
Thanks for that.
