I want to add Bluetooth

[2010AveoLT]

I actually made an interesting discovery yesterday afternoon when driving home; my Girlfriend called me while my phone was plugged into the Aux Port, and the call came through the speakers as if I had Bluetooth; and now I'm wondering if there's a way to exploit my discovery.

That should work if you have a good speaker phone.

If you look under the consol near the seat belts it should be there. The bluetooth

HTC makes a rechargeable Bluetooth StereoClip for like $40 on amazon and it looks like a pretty good deal.

I have considered it but at the time it was $80 Haha You can order it from HTC but youd have to call them at 1-888-868-4154‎ in order to order it lol

I be leave the Bluetooth is separate from the onstar. Since you said it came through car speackers when it was hooked up. I bet you might have the Bluetooth box under your consol. I think 09 or 10 cars had to have the Bluetooth in them or the option for the Hands free law.

You will not be able to do anything with the factory radio to add factory bluetooth to it, so no point wasting time looking for components. Your choice is limited to those of what I posted and then the options that you listed yourself that you aren't interested in.

An aftermarket radio is by far the best option.
