Good evening to all. I have just joined this fantastic forum after reading nearly every page. After buying a 2003 exec model I have lots of question which I will ask gradually. My first one is regarding replacing the head unit. The sat nav has the disc read error and I managed to knock a £ 100.00 off the asking price for the car so am keen on replacing the unit. My budget would be around £150 ish. After seeing some good looking prices on eBay I am excited at this being possible. However I really don't know which one to pick. Could anyone perhaps recommend a unit ? Would make this feeling of dread go away.
