Has anyone upgraded your bluetooth microphone? (for those w/bluetooth factory equipped)
I find that while functional, it sounds to others like you're in a cave and has an overall 'hollow' sound to it.
There are a few places that sell upgrades to our microphone such as this -->

Has anyone tried this? For around $60, it seems like a no-brainer to do. The microphone in our unit is super last-gen (as is the Nav etc). So for anyone on the phone as much as I am, this may be worthwhile. Opinions?
