I'm hoping some of the car guys can help me out here. I need to upgrade some stuff in my car and I'm hoping to do it all through a new head unit. Basically I need: 1. iPhone hands free kit 2. iPhone/iPod connection 3. SatNav I have a budget of about £300, ($450) but I've never purchased anything like this before. I am aware that my budget may not allow for SatNav but I can hope! Help, advice and suggestions would be amazing.
