I am a noob so forgive me for sounding stupid. Last week I bought my wide a 2005 V8. It has a few issues to fix (seems like the standard stuff from what I have read, running gear fault and some speakers that don't work). There are 2 buttons on the back of the steering wheel. The one on the right appears to activate the heated steering wheel, at least that is what the icon on the dash indicates. What does the one on the left do? I have owned nice cars, but never on with so many "toys". I love it and I hope that with the help of everyone here I can ge them all figured out.
