OnStar told me that my '04 H2 has an analog system and it is upgradable to digital at the dealership (05-06 are already digital). They said that the only deal they can give me right now is with a three year subscription but since they are going to 100% digital in a two years, I would need to do the upgrade now. They said the upgrade is free with a three year subscription but I would have to do it all at the dealer.

Anyone else going through this and have some advice.
