I have made the stupid mistake of allowing iTunes to update my nano to firmware 1.1.3, now it will no longer link to my Alpine car stereo. I have trawled the web and seen other with a similar issue. It seems I need to downgrade to version 1.1.1 and all will be well. I have downloaded iPhone1,1_1.1.1_3A109a_Restore.ipsw iPod1,1_1.1.1_3A110a_Restore.ipsw both of which fail as being incompatible. In desperation I downloaded iPod_22.214.171.124.ipsw iPod_126.96.36.199.ipsw again, both fail for the same reason, incompatible. Any help anyone can give me to get me out of this mess would be appreciated!
