I had a 2005 Infiniti FX35 which I traded-in for an 2008 Infiniti EX35. Best trade I ever did! I will post pics of my ride before and after mod as soon as it is finished. Right now, I'm just enjoying driving the EX around.
By the way, just for reference. I have an IPhone 3G and syncing it via Bluetooth to the EX was easy, but I could not transfer the phonebook/contacts to the Navigation System or have Caller ID. So, I went to the Infiniti EX website and looked at the compatible phones for Bluetooth sync. It turns out that one of the best phones to sync with the EX is the Nokia N75. This phone will work well with the Bluetooth on the EX. The only feature that this phone will not perform with the EX is call waiting. I can live without it - the other person calling can just leave a message. Anyway, my mobile service provider is AT&T and they are selling the Nokia N75 right now for $49.99. So I just added another line to my current plan which is $9.99 extra per month and switched to a Family Plan. Voila, now my EX has it's own phone number. The Nokia N75 is always left in the car and can be charged through the car charger.
In my opinion, it's the cheapest way to have a true car phone with it's own dedicated number...
