Received mine today at 9.20am after ordering yesterday midday!!
Took out the head unit and and wired up the amp - but the cable block that slots into the back of the head unit wouldnt fit flush enough so that the locking device would click into place. The device works when unplugged but not when plugged in - I even tried the cable blocks plugged into itself - as it only a piggy back device - and even then it still wouldnt lock!
Rang Bluespot who didnt initially believe me and blamed my car and then gave me a premium rate Blaukpunkt technical support line - they were of no use either but agreed it must be faulty if it didnt lock into place when plugged into itself. So back to Bluespot who have agreed to look at the cable block if I send it back at my own expense and check it against the standard block - WTF!
So now i'm over £300 down - have half my dash on the car floor - and faced with the possibility of them fobbing me off with a faulty cable block. Of course they could say it is faulty and replace it - will have to wait and see!
The only good point is when holding the cable in place I could hear the difference in the sound quality and was impressed with the amp - just hope I get a new cable soon so I can fit it up properly!
