Had the unit checked over by Prolek ( N D Haigh) Hudderfield and they agreed its working just fine just aint picking up the satellites. (Instead of it not recognising at all where I am, I have somehow managed to set its location as a small town in the middle of Germany as I was playing around with it!!)
So narrowed it down to being either be the connection at the back of the unit or to the antenna on the roof, or a dodgy antenna unit itself.
Any tips on cost of new antenna, where to get it from & how to get to the base of the aerial to replace or check connection - I guess will involve pulling off the interior cloth to the underside of the roof, not got a clue where to start pulling either!!
Had the A/C checked out whilst it was in as not blowing cold, they reckon it will need a new compressor, costing £475 all in - sounds a little heavy to me, or is that about alright. That's including the cost of stripping down then putting back together as they didnt have the parts in this week.
