I'm considering activating my onstar system again just to regain the use of the hands-free cellphone. My question though, is how much does it cost to share your minutes on a verizon wireless plan with your car? I know you'd have to add your car as a second line, but is it the regular rate of 10/month? Onstar is 17/month, so the two together would be close to $30/month for onstar/hands free cellphone in the car using onstar. (the person you're talking to plays over your car'* speakers, and there'* a built in microphone in the rear view mirror I believe.) The reception is supposed to be superior to cellphones because it uses towers from ALL service providers since Onstar is a safety system. Has anyone done this? I'd be really nice to use..

Looks like you will need a basic On Star plan in place for your car and you will need to add the On Star number as a second phone on your Verizon account.

From the On Star website:

Now there'* a wireless plan no one else can offer. It'* the Verizon Wireless America'* ChoiceSM Plan with OnStar, a Family SharePlan that lets you share your Verizon Wireless Plan minutes between your wireless phone and your OnStar Hands-Free Calling.

An extra $10.00 is a small price if you have a plan with a lot of free minutes. The least expensive add on cost per minute for the On Star is 1000 minutes for $299 or .29 a minute. Way expensive.

My 03 SLE is not digital, it is analog. I can have it upgraded to digital for 3 years of onstar service prepaid(about $600 for cheapest service). In a couple years though the analog isn't suppose to be supported anyways, but $600 is a lot to pay just to add my verizon to my car.
