slocko - I presume you currently have a hand held cell phone. As such, contact your cellular provider and find out where they do installations. Go there and look at the alternatives.
What is typically done is they can install a cradle for your current phone which will hook up to an external antenna, a power booster, an external microphone, and a battery charger. They may be able to hard wire into your audio speakers as well.
Good Luck
