Navigation to In-Dash – myGMC Review

This app only seems to work sometimes and if you don't update it. My app worked fine until the latest upgrade and now I can't send Navigation to the In-Dash unit. Hopefully it will be fixed soon. UPDATE - After multiple emails and phone calls all of a sudden (like others) I have the ability to send directions to my In-Dash unit again. I see there is another update but I am hesitant to download it in case I lose access again.
