I have a 2007 Volvo S40 T5 that was recently purchased. The factory navigation system reads "no disk," in order to solve this problem we ordered a new disk. The new disk is inserted into the Nav reader, but the nav system still reads "no disk," and when I try to eject the disk nothing happens, the two green lights do not flash they stay solid. If anyone can point me in the right direction to resolve this I would really appreciate it! If all else fails, I plan to take the unit out and try and remove the disk manually.
