Oh, I believe there is a way to adjust microphone sensitivity. You may want to contact GROM support, maybe they could let you know how do do it or they could provide you with a custom firmware to improve call quality.

Thanks I will contact them. Also do you have to manually pair it or does it pair automacilly for you? Seems I have to pair it manually every time I get into the car.

Try resetting the GROM unit, & try the "forget this device" button in the bluetooth menu for the GROM unit and then re-pair, it may help with your phone not reconnecting automatically.
To reset the GROM unit:

Mine did not go all the way in, mine stuck out about half a cm. However, I haven't had any problems with calls. But my friend did have the same trouble with syncing the bluetooth for the iphone 4s.

What problems is your friend having with syncing?

Has to re-sync each time. Then again their phone has been faulty for a while so it is more than likely just them. But yeah I went back and forced it and its an extremely tight fit but no one seems to notice any difference in quality of phone calls from the bluetooth.

I just updated the firmware which updates the bluetooth so far seems like it connects now. Tell your friend update the firmware on the grom.
