Some companies continually change their contact details, so please feel free to update the On Star listing at any time if you have new information.Comparing On Star to Google maps, it has been my experience on this trip that On Star maps have been less accurate.On several occasions, exit numbers on On Star have been wrong, roads have been mislabeled, and routing has been circuitous.

It's the year 2016 and I know there are better roads than the 2 lane winding road that they put me on.

I pay a fee each month and you would think they would use that money to purchase a current map. I spent about 20 minutes with the first representative, but she had to transfer me to the technical team for better support.

I am having a Horrible experience trying to get my new truck set up in the GM system system will not allow me to use my email address stating that the user name was already taken. I was courteous and provided my cell phone number and it linked to your GM system.

First I was told that my email account was linked to my wifeââ? ¢s account and we would need to link both accounts together.

I've never had a problem with my Bluetooth so I probably will let this one go.

Someone posted a similar discussion on the Camaro5 forums. Onstar bluetooth update letter - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums - Camaro5I assume this is what GM will do when the new i Phone is released and cars can upgrade to work with the 'Eyes Free' feature.

The lists includes numerours phones, including i Phone 4/4S.

Please find On Star customer service, technical support and customer support details below.

Then I was later told that my email was not linked to her Cadillac, but it would take 3 to 5 business days to update the On-Star system !!
