I can confirm that auto-routing IS possible with Mapsource TOPO (NB I'm talking about Great Britain version only), I have done it using a Vista Cx! [edited with more detail given after the following question]

I'm interested to hear from anyone that has been able to compare screen refresh rate/scrolling speed on Lowrance's iFinder dual processor units with, say, the comparable Garmin unit. I'm thinking Expedition C vs MAP 60 CSx for instance. Are there any other notable benefits from the dual processor set-up?
