Resource scanner not working

[Clockwork13]

I'm using the M4435 resource scanner in a polar orbit around Minmus. Everything seems to be fine, but there is no button to perform a resource scan. Am I missing something?

'Fraid so. The Narrow Band Scanner can't perform basic resource scans. Only the M700 can do that. Once you have performed a scan with an M700 in a polar orbit, then you can bring out the NBS and get a detailed resource mapping from any orbit you like.
