Hi everyone, in need of some help with the above satnav. Bought Laguna without satnav discs and purchased some from Ebay. Loaded CD1 and received 'loading' message, followed by 'attention' but the display missed off the rest of the message. Ejected disc, switched off radio, switched it back on again and the radio will not work. I've taken out all the relevant fuses, disconnected the battery but no code input appears. Screen just displays time and temperature constantly and the disc slot lights up. Please please can anybody shed any light on this? The silence is killing me! 
Thank you.
Thank you.
