Since the HHR comes with on star and on star gives you your own phone number, has anyone called from their HHR to another HHR?

Silly but I think it'd be funny!

 

And what does the Caller ID show on it's display when calling from your HHR?

 

the number that your hhr is given by on star

 

I've called my HHR from my cell phone while my girl was driving it around town. It's just another phone number... kinda the coolest cell phone around. :)

I've not yet called another HHR from mine, but it shouldn't be hard to do.
