Whats Tel1, or, how can I get a handsfree phone in my car?
There are a couple ways to integrate a cellular phone into your vehicle, depending on what country you’re in, and what level vehicle you have. It quite ridiculous the lengths Saab has gone through so this is as difficult as possible. But where there’s a will, an international forum full of enthusiasts, and good ol fashioned gumption, there’s a way. For discussion, it must be noted that TEL1 & TEL2 are different.
