Ok, this is what I'm thinking of doing: My 2001 V70 has the centre speaker grille which I think doesn't have a speaker behind it. I would like to use the space to install a sat nav. I'm not thinking about the vertical sliding arrangement of a factory fitted unit, more of a rear-hinged pop-up lid which will reveal a cubby hole in which will be a (removable) Garmin Nuvi. My current plan is to simply cut a rectangular hole in the grille (from above) as big as possible, neatly fold the edges of the grille in (so that there's a neat edge), and then build a (wooden) lidded box that would go inside this. The lid of the box would be covered in leather/vinyl, and when closed would be flush with the grille / dash. Ideally the lid would open on a motor connected to the ignition. My aim is to have a SatNav which wouldn't be visible when the car's parked, but wouldn't need removing every time I park, but could be removed if I wanted to use it in another car / bike, and wouldn't have any of that cigarette lighter nonsense. So all the advantages of a factory fitted unit, but without the ludicrous expense, and with the added advantage of beiung able to take the unit out. Has anyone else done anything similar, or is there an aftermarket product that I could buy? Dz
