Could do this simply on my 2012 SRX. Now have a 2015 SRX and it is a nighmate trying to figure out how to dial an extension once the call is dialed! No one at Cadillac has an answer. Everything they have suggested does not work. It is against the law here to use the touch screen while driving! What don't they understand. Very frustrating. Have had the car 2 weeks.....need this feature for business....on the road a lot!!!
