I make a lot of business calls usually while I'm in my car. How does the iPhone work with a 2005 Command unit? Bluetooth? Or do I have to do some aftermarket stuff?

 

Works just fine with factory bluetooth

 

Was bluetooth an option or does it come with navigation? Can I still purchase the hardware separate if so?

 

It works OK. It pulled the phonebook over without problems, and connects without too much fuss.... Until I switched to iOS5. Sometimes I have to power cycle the bluetooth on the phone to get it to connect. Other than that, it works.

My only complaint is the AC/Heat on full blast can make it hard for the other person to hear what you are saying.

 

We have the upgrade kits to add both bluetooth, iPod and music streaming to your car (all one device) called the iTronic BT.

If you need it
