Is it possible to install an aftermarket in-dash navigation system (for example from Pioneer, Kenwood, etc.) into a 2008 Volvo S40?<p>I've been searching the internet, and this forum, and can't get a definitive answer. Some places say no, some say it's difficult, some say you can. It seems the console makes this difficult. Is this Volvo single DIN, double DIN, or neither?<p>Thanks!
