Hi, I am the new owner of a 1.6 Picasso Desire - I've had it a couple of weeks and am generally pleased with it. The radio reception is awful, but having searched these forums I have a few aerial related things to look at so I'll sort that. I have another question though ... when I turn a sharp corner I hear something sliding across inside the dash. I wondered if somebody has dropped something through one of the air vents - so how do the air vents come out without getting damaged? Also on the left central vent the chrome plated plastic control knob is missing - if I visit a breakers is this an easy replacement? Can I just replace the wee plastic bit or do I need the entire vent unit? Thanks to anybody who can help me with this.
