: Factory Installed Analog Phone Outdated?

I recently purchased a 2000 DTS. It has a factory installed phone in the center console. I called a cadillac dealer this morning to find out the procedure to activate the phone. He said that becuse the phone is analog and not digital that it cannot be activated. He also told me that my onstar feature on this car cannot be activated. I am looking for a second opinion.

Unfortunately, he is correct. The early onstar units used analog cellular communications which was discontinued completely by the FCC earlier this year.

Check out my thread on bluetooth conversion in this forum, perhaps that might interest you.

2002 is the turnover for the analog-digital conversion. Nothing earlier is supported.

You could modify it to work correctly though, As long as your OnStar uses the Class 2 data bus and not the older E&C data bus.

This is the best i could decipher. A friend of mine did the conversion on his truck and it worked flawlessly..
