When I dock my 1st gen touch to the Altec Lansing iM310 and turn the speakers on, a message blinks continuously on the screen: "This accessory is not supported by iPod". However, the speakers work and the touch charges. The problem is that I am unable to operate the iPod with this message blinking. If I want to change playlists or songs, I have to power the speakers off, operate the iPod and power the speakers on again. The iM310 is supposed to be compatible with 1st gen touch. I've been in contact with Altec Lansing support all week, but haven't found a solution yet. Does anyone know why this is happening or how to cancel the message? Thanks for your help.
