Hi all, sorry if this has been asked before, searched a bit and couldn't find anything. So my SatNav on my Columbus unit hasn't been working (0/0 Satellites) so I bought a replacement GPS Antenna from eBay, fitted it a few days ago and now about 2-3 minutes after starting the car the screen starts flickering on/off as if it's rebooting but not actually restarting (music cuts out and screen goes black, this happens even when the screen is 'off', ie with the time showing and nothing else). I've ran a fault scan with OBDEleven and the only related fault is 00856 - Antenna, on Radio - Short Circuit to Ground - Intermittent. I've swapped the old antenna back in but the problem is still there. If anyone could offer any potential solutions it'd be very much appreciated, thanks in advance!

 

 

 

Bump. Any suggestions or am I best replacing with a new unit? Thanks. 

I am having the same issue, I had mine sent away to have it looked at, they updated the software and came back but still does it, I am still trying to figure this out.
