Making My Garmin Nuvi 200 Sat Nav Look And Feel Like My Tomtom Go 910 Sat Nav?

I have an ageing and slightly dickie TomTom Go 910 Sat Nav and I want to know if I can basically ‘transfer’ the ‘operating system’ to my newer and slimmer Garmin Nuvi 200 Sat Nav i.e. so the Garmin looks and feels like the TomTom – is this possible or am I just wishful thinking???
