Hello Since the old RTI Navi (with the 6x CD changer) gives up the mind so slowly, I would like to exchange the extendable monitor for a portable Navi device. Has anyone done this already? Is there any experience? The problem with RTI: Reading errors old card material aged operation Constant problems with the location determination repair too expensive! The plan: I would like to disassemble the extendable monitor and safely disappear in the cavity of the dashboard in the connected condition Now I could install a portable Navi incl. connection cable in the frame. Voltage via ignition plus, operation via touchscreen, sound from the Navi own speaker. So I would have installed a current navigation device in the car, with 3D, new maps etc. for small money (and probably a lot of work). I would not remove the Volvo components and so w w It would be nice if you could give me help with this project Lg Tommy
