RNSE 0 gps satellites found?

ok I have the RNSE unit fitted from factory, after a year of ownership of my current 2005 s4 cab, it's starting to misplace me. Sometimes im on another road sometimes in a completly different county! So I keep resetting the start position when I get home so I know I'm exactly outside. But after a short drive I could be anywhere. I read about fitting a new gps aerial so after following some links I bought a puck style one, about £25 so not a cheap i unit. I pulled my stereo out and checked the nav map it was showing me as being about 1/2 mile in the sea! So I plugged in the new gps turned off, done a reset of the unit by holding in the nav and setup buttons together, all fires back up and nothing im still parked in the sea! I go into engineering mode and under nav info and gps I have no satellites found.
With new puck type


I also forgot to say it's a brand new 2014 sat nav disk

Ok will give it a look tomorrow.

Well i ad a look over the weekend and everything seems intact, is it possible it needs the genuine audi antenna?

No i don't and don't actually know anyone who has, apart from a dealers and after the last £720 bill for my last service, i'm keeping clear of them for a while..lol
