sorry to sound stupid. But, what is bluetooth? what does it do? something to do w/ cellphone? Will it work for a 2003 E320?

 

You may be able to get a kit so that your cell phone can talk to your car through a wireless technology called bluetooth. (Think of it as an infrared connection except you do not need the line of sight. Not all cell phones have bluetooth, the Sony Ericsson P900 has it, the Treo 600 doesn't.)

I don't believe a complete factory bluetooth car kit is readily available at your local USA MB dealer yet. My understanding is that it is a European part and requires some messing around.

However, the idea is that after pairing up your cell phone and your car kit through bluetooth, once you are in your car, your cell phone's incoming calls will be automatically transmitted to your in-car speaker phone and the system will even mute your music for you.

The typical disadvantage of such bluetooth system is the lack of a numeric keypad for outgoing calls (many cars do not have a 10 digit numeric keypad unlike your MB); in addition, bluetooth does drain your cell phone's battery rather quickly, and finally, unlike a wired telematics system such as the MB V60, your bluetooth cell phone will not have better reception in your car as it cannot take advantage of a booster antenna.

 

I see!!! sounds cool! But, I probably better off using my ear piece!!! Thanks for the info

 

... and in response to the obvious question,

... supposedly because the Bluetooth standard "consolidated" several competing standards for short range "personal area networks" (PANs).
