06 Envoy

where can i download the avic d3 east coast nav disc or can someone sell me one or seed? thanks Jason

i used a scosche dcgm09 interface i didn't care about onstar i also used the 4 channel bose factory amp

tried all that it still doesn't work ughhh i even reset the unit my phone bt unit will mute the radio on incoming calls but nav doesn't even mute

i wonder if i have the wrong disc i'm running the 70mtp discs it routes fine and the screen comes up to tell me when to turn but no voice could it be the wrong discs and if so where can i get the proper ones? thanks

what is the disc number for a D3 is it CNDV-70MTP

the bluetooth unit will mute the radio on incoming phone call that all works fine so i am clueless

its running out of the avic to the adapter which has 4 channel inputs

the bose is a 4 channel amp

the mute never happens i'm running it through the front outputs i can hear the beeps fine but it never mutes or has voice

on ya i forgot its in an 06 envoy with factory bose

I can't get my voice guidance to work. The beeps work fine. I have reset the unit. My current setup is avic d3 with gm os adapter to bose amp. The music plays fine. I have set it to max volume guidance on and mute in the main initial settings. What am i doing wrong? UGHH!!!
