What's the biggy about the basemap?
 

So a Garmin 60Cx costs £360 in the UK but £260 in the US... and the only difference is that the US one has a US implanted basemap whereas the UK one has a Europe basemap.

But if you are doing a RTW trip then the Europe or US map is useless anyway as you wont be using the basemap of either of those regions. And you have uploaded the local maps via mapsource anyway.

So even though I'm in the UK I might as well get the US one and save £100 and head off to Africa.

So what's the use of having the Europe basemap in Europe anyway....you are half a mile inaccurate anyway.

...or am I missing something?

Nope.
I think they only provide the basemap to justify the price...
I bought my 276c in the us and saved a bundle over the UK/EU price.
Bought two 256meg chips at €60 a pop and loaded them with Worldmap segments and European City Nav segments.

Basemap never comes into it.

Just watch out for import duties and VAT though as they can hit you hard...

They certainly do... I got mine while I was there on hols.
