I have installed the car kit or rather had it professionally installed since it is integrated into my cars electrical and audio systems. The device faceplate can be located conveniently to allow use of the controls with minimal distraction from the traffic. To date I am very pleased with the unit. After the initial mating the devise will automatically activate when ever I get into the car with my cell phone on, in addition it can configured to accommodate up to four other cell phones so every member of the family can be hands free legal. It will also allow voice commands and will dial the number from your phones address book without having to reconfigure your phone list. This unit is a bit pricy however if you spend a lot of time in the car talking on your cell phone it is well worth the money.
