RNS 310 Lost GPS position

[matada34]

Hi,

I have a 2011 Passat with the RNS 310 fitted, this was fitted at the factory from new.

I've never updated the maps so it's still V1 however a few weeks ago the sat Nov lost its gps position. It thinks I'm in Wales or the sea, I live in Staffordshire! This happened over night with nothing untoward done on the car, e.g. Battery disconnect or going flat.

I've looked around but struggling to find what may have gone wrong, any thoughts would be great!?

I've done the factory default reset but it made no difference.

Thanks matada
