Is anyone using a Blitzsafe iPhone adapter with their 2003 CL S-Type with CD changer and navigation unit? I want to charge my phone and play music through the car stereo system. If so, exactly which model are you using and is it 100% compatible? Also, any installation tips/instructions would be helpful. I'm getting real tired of hearing the wheels turning in the cassette player when using that adapter (and it doesn't charge)!
