Phone on Laptop

My wife has a car that when her Razr rings it displays the caller on the radio screen via bluetooth and she can talk handsfree (mic in rear view mirror). I got a laptop with GPS on it and wondered if there was anything out there that would do the same thing on the laptop? My phone is also a Razr and the laptop is not bluetooth enabled but phone is. I don’t need to upload or download, just want to use the laptop for speaker and mic, maybe display the caller info. Computer is a DELL Inspiron 8100 with XP pro.

Thanks
