Hi Everyone, Sorry if this post has been answered elsewhere but I'm a newbie & this is my first post. I had a factory fitted Alarm installed a few years ago by Subaru Ringwood, a few days later after I picked it up I noticed the Navigation wasn't working it displays "Error; System unable to access the program. Please insert proper disc" I obviously called them, they did nothing but muck me around for 3 months and never fixed it, so have lived with it not working for four years. Now I am looking at selling my car I am wanting to get it fixed. I have the disc which was in there when I purchased it (S/H in 2012), it's a denso Whereis AUS 20 I also recently managed to get my hands on a Subaru Liberty 2003-2009 & Ive also tried a Tom Tom V22, neither works. Subaru Doncaster (last week) have said it may be a V25 that is needed but not 100% sure either. I don't want to pay $200 for something that may not work either. Has any one else had this issue or have a V25 that they wouldn't mind me trying please. Many thanks, Linda
