1. It sounds to me like the voice guidance replaces the music in the front left speaker. I agree, it's hard to hear if the music is loud in the voice-tone, mid-ranges. Not a resolution, but a simple work-around is to simply press the "map" button, and the voice guidance will be repeated. (I usually turn the music down, prior to doing that.)
2. I remember seeing an optional setting in the Nav that I inferred would eliminate some of the mundane repetitive announcements. Might be called 'advanced mode', or 'expert mode' - something like that. I did not try it, because I was unfamiliar with the system at the time. That setting might help you out. If you find it, and try it, please post the results for our information. I don't use voice dialing, but might try it myself for the other times when Miss Nav decides she needs to state the perfectly obvious!
Russ,
I use voice dial by number and it works great, you say the number the voice repeats it to verify and dial it..
The navigation voice can be turned up so loud everyone in the car can hear it... The voice prompts can be turned off completely if you know all the steps and don't need them..
How does one turn off the voice prompts COMPLETELY? I haven't found that setting. Only one that turns off the initial "please state the command" question.
Thanks,
Russ
