Hi I have my eye on a 2005 Estima 7 seater with leather/vinyl seats. It is a thing of beauty BUT.............. I really really dont want to buy a car that has useless devices in it So, my question is this...... Has anyone replaced the original factory fitted Sta Nav/Reversing Camera/DVD/CD player with something that gives you all these options plus an input for my iphone so I can receive phone calls hands free and play my iphone music??? Thank you for your help
