Voice Command not working properly. Screen goes black. Cancel NAV?

1. Pressing the Voice Command button on the left hand side of the steering wheel only works when Audio is turned on. Is this correct?

2. Go Home from Voice Command replies "That request is not available at this time". Sometimes. And other times it works. Is this normal?

3. When Audio is on, and playing SAT, FM etc, using the SCAN feature works fine but the screen goes black after a second or two. Makes it hard to see the song/artist. Is there any way to change the screen so it stay on longer. Staying on forever and letting me choose SCREEN OFF would be even better. It's hard to stop the SCAN when the screen is black.

4. How do you cancel a Turn-by-Turn navigation prompt before reaching the destination?

I've looked at the books and videos and serched here but just can't find the answers to the above. Anyone?

 

Maybe it's time to visit the service department?

 

Thanks for the responses everyone.

Thanks Diane.

I think you answered the Go Home question.

The screen goes black after only a few seconds, headlights on or off.
After pressing SCAN and scanning the channels on the radio (FM, AM, SAT)
I hear a piece of music that I like
but the screen goes black
so I can no longer see the SCAN icon at the bottom
so I can's stop the scan at the station selected to enjoy the song.
If the screen stayed on, I'd be able to stop the scan by hitting the SCAN button.
Is there a way to have the screen stay on permanently and not go black until I do something explicit?

I'll try hitting the destination button again to cancel the turn-by-turn in progress.
Will advise.

I lived in LA for 18 years but prefer the SF Bay Area having lived here for the last 20.
But next time I drive down to there I'll be glad to stop by.
Thanks for the kind offer.

ps
Regarding the first question
Pressing the Voice Command button on the left hand side of the steering wheel only works when Audio is turned on.
I'm almost 100% sure it works sometimes when the Audio is off.
It seems a bit inconsistent.
Likewise, saying Go Home to Voice Command sometimes works even with NAV and everything else off when the Voice Command button does work.
Make sense?

 

Had to drive the SRT-4 for a few days to get closer to 100K on Stage 3.
Back to the Pri this morning.

"Press the destination button again to cancel routing - it says there at the top delete destination". That solved the problem. The thing that threw me was that it asked "Delete Destination". I thought that meant delete the destination completely. What it really means is for it to cancel the the current Turn-by-Turn navigation prompt. In other words stop it before reaching the destination. It works, yipee. The NAV system is pretty cool, at least as good as my old TomTom.

As for the Display Screen going black, I think they want us to program the radio station selections while parked and not while moving and then use Voice Command with the Select Up or Select Down to change the stations that have been pre-selected. Sort of Obama-Radio. Or is it Gingrich. Whatever. It kinds make sense now that I thought about it.

Everything is nirvana again. Must say I love the sound quality of the JBL. Really enhances all those cool background snaps and clicks on that Lionel Richie song All Night Long. I usually listen to EC. But this was on my Ann's IPOD. Diversity is good for me

Thanks everyone.
