How does the sat-nav in the Connect Nav+ compare against a TomTom or Garmin unit?

I have recently acquired a Hymer motorhome based on the Ducato 2.8JTD. It's a 2005 LHD auto imported from Germany and only has the map CDs for Germany. Without the UK map Cd I haven't had a chance to try the sat-nat.

We intend to tour around Europe so would have to buy the full set of CDs from Navteq at £217. Would a general purpose, transportable sat-nav like a TomTom be a better buy even though it would cost more?

All opinions welcome.

Pretty sure the cds are cheaper than that from other sources cough cough.

Perhaps so, but I can't find any at the moment!
