60CSx error: no roads close to start

Please excuse the n00bness of this question, but I have recently
purchased a 60csx in the US for use in the UK.

I've installed a TOPO GB map onto it as well as sticking in a 1gb card to boot.

However - whenever I ask it to navigate to a location (sticking to the
road), it tells me that there are no roads close to start point. This
isn't so, according to the map nor the actual location.

Any help much appreciated.

Sounds as if the unit is attempting to use the basemap for the routing
rather than the Topo-GB maps. When you downloaded the detailed maps to
the 60CSx, did you make sure the box asking whether routing data should
be included had a checkmark in it? Otherwise the unit will display the
maps but won't have some of the data needed to use it for auto-routing.

For Garmin's Topo USA, the roads on the topo maps will not autoroute.

If I have the basemap turned off, the topo map turned on, pick a
destination some distance off, and tell it to use a follow roads route
it reports a "Route Calculation Error: No roads near starting point".

when I press OK it gives me a off road or point to point route. The off
road route crosses a number major and minor roads, one leg in a straight
line, to get to the destination.

If I turn the basemap on and do the same thing, picking the same
destination point, a follow roads route starts on a nearby highway (not
at my fix, it leaves me on my own to get to the starting point on the
highway) and then shows a route with two point to point route legs that
get me to the destination.

The purple lines that mark the route are straight lines from one point
to the next, they do not match the road's curves as they would with
follow road route on the basemap.

So I don't consider follow roads routes to be useful with the topo map.

I also have City Navigator maps on the GPS, if I turn CN on I can't see
the topo details (contours lines, etc.). So in use, to use the topo
maps, I generally choose Shown None to turn all maps off and then turn
the topo map on.

There is a Show All choice for maps but you can only see one map at a
time and that will be City Navigator if that is present. If there is a
hierarchy for displaying maps when multiple maps are present, I don't
know what it is.

That's true for Garmin's Topo-US, but not for the Topo-GB product that
the OP has.
Topo-GB does support auto-routing provided the user has 1) unlocked the
maps for their GPS receiver, 2) selected to download the routing data
along with the map data, and 3) downloaded the appropriate map tiles
that cover the area of the planned route.

I use TOPO GB for both "Off Road" & "Follow Road". The "Follow Road"
works fine. I now have the whole country loaded on a 2gb card, with of
course the Routing box ticked. It has coped with a new road taking it
into "unknown" ground. The only problems I had were of the missing tile
type. Even then it once directed me round the corner of a missing tile,
but it has crashed out when I left the tiled area. That was when I
first used it with the 60CS and then the x with a smaller card.
