So I just recently bought a Nissan Sentra (2007) and it has an auxiliary input and integrated bluetooth (that I leave paired at all times when I'm driving). I love it! Except for one thing.. when I hold the home button on my iPhone 4 to bring up voice control, once the blue screen is there my car decides to switch over to bluetooth mode and I cannot use any commands to say 'play an artist,' etc. So basically, does anyone know of any apps that offer alternate voice control (for the iPod app), that can be activated by one of the buttons on the iPhone? Thanks!
