Forgive my ignorance...I'm a neophyte.....(1)Is the intergrated phone option available on the '97 528i...(2)for use with digital, CDMA/TDMA (SMS, email,etc. functions), telephones....(3)other than the factory BMW Motorola StarTacs? (What about Nokias, I've got the 8860 & 8260)? If so..how do Nokias fit into the system?...modifications needed? Please send detailed info........Thanks.
