Hi, This may be a silly question, but I am interested in purchasing the N3. My understanding from looking at the website it that the DVD is needed for navigation. If you want to listen to CD then you have to switch out the DVD for the CD. If you are listening to a CD and want to find a point of interest, you have to stop listening to the CD, switch out the CD, insert the DVD and then search. To me it seems very time consuming and impractical. Am I wrong? Thanks
