Rns 510 - no map display - screen white / black - all else works

Did you try this

Settings/ factory reset/ scroll down to navigation and navigation memory.

Tick them and press reset

Other than that you could reset the whole unit back to factory from that menu but i guess you would lose all settings and maybe music etc

Yep done all the resets possible, think I will send it for repair at this stage, guessing the GPS board is screwed.
The difference between it working and not working was a dsg transmission service, I am guessing there is nothing they could have done to screw it up?

I have purchased 2 RNS GPS antenna from these guys and a friend has purchased another also. All perform faultlessly.

get4less_shop on eBay

for the price of an antenna...I'd try that first
