Hi,

Hopefully someone can help me with the Nav on my 2006 IS250 AWD

My navigation system was working well and suddenly did not work a few days ago. The maps work, but there is no voice-guidance. Everytime i set an address, it will say"voice guidance will start when on blue line" but after that there is no turn by turn voice. I even click on the map/voice button and there is no sound as well. The only sound i will hear is when I am almost reach my destination it will say "you have reached your destination".

Another issue as well is that when the route guidance is on, even if i take a wrong turn it will not re-route on the screen. It will just show me travelling the wrong route with no blue lines to lead me back to the right direction.

I have checked all the settings that the Auto Voice guidance is on and Voice Guidance in all mode is on as well. I even tested the volume and hear the voice guidance lady with no problem.

Please advice as I cant seem to find anyone having this problem.

thanks,
ed

 

I'm no expert, but you might want to try pulling the neg. battery cable to allow for a reset.

 

No luck It's still not working after disconnecting the battery.

I wonder if its the Vaistech SL2iC that is causing the problem? The I agree button on the Nav now is pressing all by itself even when i don't have the iphone plugged in.

Man, i would hate to have to rip everything apart as i remember it took me almost a whole day to do it when i install the thing over a year back.

Does anyone have any problems with their Vaistech causing their Nav to be messing up? Or any other ideas why the route guidance is not working??

I need help

try taking out the nav dvd and putting it back in

 

Almost certainly.

 

Did u put a gps override switch in your car?

 

When does voice command and new blue line appear for re-routing? It is annoying to blow past an intersection and hearing/seeing guidance that will not recalculate quickly and adapt to new "best routing."
