Haven’t noticed any problems with reception (although only done a few miles since fitting). Does anyone actually know whether the roof aerial does AM/FM/DAB and the GPS signal?
On my ST, I am sure the DAB aerial was embedded in the rear quarter window (my ST did not have privacy glass so it was clearly visible) – obviously can’t tell on the RS due to the privacy glass.
Concerning washer jet fitting – I unclipped the two clips on each side that hold the deadening material (under the bonnet) in place and this gives enough room to comfortably get your hands in. The wiring harness simply pulls apart relatively easily but you need to give the pipe feeding the water to the jet a fairly hefty tug (especially the passenger side). Once disconnected a push from the underside and the washer jet simply pops out. Fitting is the reverse.
