I just bought a nav5. VERY strange problem. When I copy and paste mp3 songs (created in iTunes) from iTunes, they play fine. When I copy mp3 podcasts in iTunes or audiobooks in mp3 format . . They playback super fast. I called garmin and they have never heard of it, nor did he even know what a podcast was. Can anyone confirm they have actually copied over and played a podcast and it's worked correctly? If so I will exchange the unit. If it's a software flaw, then could be a longer term thing and as podcasts are super important to me, might rethink. Works fine on my old zumo.
