Hi, not good with computer so apologies in advance!! I have just bought a Grand Voyager mk 5 2010, got a couple problems and wondered if anyone can help, the seller said stereo volume is either on full or off although switch shows it working on the screen, he said it needs a stereo amplifier so I got one off ebay, but I can't find where it is to replace it!! Help please!! Also key fob remote central locking works but temperamental, two new batteries don't make a difference, any help would be much appreciated, regards Poolman.
