Q:I’m interested in purchasing the pop up navigation screen and system for my 2007 Volvo S40 can you assist me with this and how to install it such as suggestions and difficulty? 

A:There are few different ways that you might use it, you could connect other device to it like dvd player but it will involve custom harness that somebody would have to make, you could add navigation but you will also need navigation player, gps antenna and remote, you should also check if you your s40 is prewired for navigation otherwise you will need wiring,
