The navigation system may stop reading the old disks. You can keep the screen inactivated and get it back down by using the button behind the steering wheel. Noisier than my 4Runner. Love the quality of the car and mine has Navy blue leather interior!
This is a fantastic all-around vehicle. It's big and comfy enough for a normal person, can haul whatever you need, can tow as much as a small truck (3300lbs), gets 30mpg on the highway (25mpg mixed), and is fun to drive (5 speed manual transmission.) I'm a Volvo enthusiast, so my opinion is slightly biased. I got this wagon for a really good deal because it needed some body work. I performed the necessary repairs and have put 40000 miles on it in 26 months. Parts are relatively inexpensive if you shop online. Places like FCPEuro and EEuroParts have mostly everything in stock and have fair pricing. RockAuto has a lot of stuff, too. There are several dedicated Volvo forums that cover just about every repair possible. I will continue to drive it and upkeep it until the wheels fall off. It's a very useful, all around good vehicle.
I absolutely love this car. It was purchased new from Phillips Volvo in Virginia Beach in 2004. I feel SO safe in a Volvo, especially their station wagons. We have one too many vehicles in our family and the oldest one has to go! Ouch! It was our fourth Volvo, and I also own a 2009 V70 sapphire gray Volvo (#5). I know the new owners will get as much enjoyment as I did - SAFETY is #1.
