Cycling in Belgium - definitely NOT spam!!!

[Rog(UK) - Yorkshire Dales]

This is a longshot. I'm going with a group of friends to Zeebrugge later this month (from the UK) and I have decided to take my CYCLE to do a bit of cycling for the day. (unfortunately, the others have wimped out of cycling)

I wondered if any of the GPS handhelds would have detailed maps which would include cycle tracks (I have a MIO 550 which I use in the UK on which I have loaded detailed ordnace survey maps, (Memory Map), but they don't seem to do them for Belgium.

At the moment, I'm doing a Goggle search, but ideally I would like either a detailed map or a GPS.

Any suggestions? I'm happy to do round route of 100 miles.

Ride safely,

Rog
