Hi guys,

Thanks to you helpful bunch I went hunting for a new sat nav unit and found what appeared to be a bargain at £35 ! Even better, upon closer inspection it appeared to be a mk4 according to a bit of googling the part number!

However, not all is rosy. When I connected the unit it sprung in to life fine, red light flashing the. On solid, accepted the disc no problem - happy days! However, the display on the HU is totally blank. It's not the HU, as without a nav attached it defaults to the 80s style display fine, which says to me it isn't the video unit either.

Before my old sat nav unit got wet the display worked fine too so I do think its to do with the nav unit.

Any ideas what to look for or who to speak to? Firmware corrupt maybe? I popped the covers off the nav and everything is healthy and dry unlike my old one. As I payed so little I really want to get this working!

Thanks in advance for any/all help!

Regards,

Toby
