Android phones have two options for connecting to bluetooth devices. From your homescreen, press menu>settings>wireless & networks (you can turn on bluetooth here)>bluetooth settings. Once bluetooth is on, you can check make discoverable or you can scan for devices (this will happen automatically for a short time after turning on bluetooth). You may need to check the manual for your home phone to figure out which one to use, but it will most likely be the scan option. I would also suggest checking either the manual or website for your home phone to find a compatibility list. I have seen a lot of users post problems with connecting to vehicle bluetooth speaker phones, and it usually ends up being a lack of compatibility on the vehicle's part.
