I now realise from [Only registered and activated users can see links. ] that you have a 3790, not a 3490, so MTP setting is not present. You have probably bought a 'factory renovated' nuvi, so to all intents it's like a new unit, in that there is no gupdate.gcd present. It appears in .system after you update as i answered in the other thread and as you've now found out.
