So I just got my 4S, got it all paired with my Uconnect system in my grand cherokee - voice calls work like a charm, music play if plugged in well...BUT if I want to use siri it sort of works... When I press and hold the home button for siri, the music quiets down, siri asks me what I want - but my uconnect dials my voicemail number?!?! So I can't use siri because its dialing my voicemail every time! Any idea how to turn off that reaction?! Thanks so much!
