Just picked up a Z140 and got it installed and all was working. it still had the original maps and my 30gb ipod video would play with no issues. Purchased an update from an ebay user and updated the maps and the Bluetooth firmware and now the ipod wont connect or is not even visible. Anyone have any insight as to what could be wrong?

Thanks

pulling the negative battery cable fixed my issues. sorry to have started yet another thread on this issue. search is your friend
