    LOL.. Ok, sorry i did misunderstand, and took your question as a noob one.

    I suspect that the quote in your post is mainly about swapping data files between versions of the same type (ie c1 v18 to an earlier version c1), naturally it's a lot more likely to succeed than swapping between types (ie c2 > c1). I'm sure you could eventually convert c2 > c1 if you have the time, skill, patience & inclination. I have time, but the skill required is way above my pay level and anyway lack of the last two discount me . I think a genuine c18 copy would surface before the job was done anyway, and the problems of sorting out the interactions between the various files and particularly of how they are utilised by the differing fw and the os i reckon would be a major stumbling block as i'm sure you know. Reverse-engineering is a younger man's game .....

    Yes. I think I'm in way over my head too.
    I was hoping that because the timestamp on the C2 map file is a year later than that on C1(V17) it could be the genuine 2012 version and only needed moving into the older working DVD.
    However, I have just dived into my archives to see what changed in the V16 to V17 upgrade last year. Unfortunately, I found that a lot of the other files changed too. Even allowing that some will be just additions/amendments to POIs or business phone numbers there are far too many unknowns to be confident of success.
    I have found some manuals on .kwi files, so I have something to read while we wait for V18 to appear somewhere.

    The map data is always a year old anyway. e.g. V15 (2009) had 2008 data..... V18 (2012) has 2011 data. You'd think Sensis/WhereIS could at least be more up to date that that when they're using their own data to compile the freaking' files. No wonder Garmin flicked them!

    Is the list restricted to the vehicles listed. As per the car logos on page one of the post there are also Whereis V18 disks for volvo, range rover etc Could it be possible that these V18 files will also update these vehicles.

    Here you go:
    Land Rover:

    Volvo:

    Maybe need to ask a dealer which disc you can use, 'coz it may not be either of the discs posted here depending on which model you have. The Sensis/WhereIS site is understandably less than forthcoming in regard to that info.

    This thread is for Sensis/WhereIS map update disc for VDO Dayton/Denso car navigation systems. CNNT AU NZ 2013.20 is for Garmin units. The two are not interchangeable so comparing them is pointless.

    I have both, CN goes on my Nuvi while v18 goes on the sat nav in the car dash!

    The same? Well, maybe, maybe not. The disc is only updated and issued once a year by Sensis/WhereIS, using the same road data as the previous year's UBD, e.g.:
    disclabelv15

    The Sensis CNNT AUNZ is still being issued 4 times a year by Garmin: 201x.10 to 201x.40, for now that is. Garmin has dropped Sensis in favour of Navteq (hooray!) so it's reasonable to suspect how 'updated' the newer issues are in fact. The Navteq 2013.20 on the other hand certainly has more up to date road data than the Sensis 2013.20, and has way, waay, waaaay, more up to date roads than the V18 (2012) disc. POI's might be a different story for the present when comparing Navteq and Sensis versions however.

    Thank you kind Sir.
    To say it politely, Thanks Mate. You are a bloody LEGEND. With respect.
    Now everyone BURN IT SLOWLY. 2x or 4x only.
    At higher speeds, the track is burnt to the DISC faster with less time spent checking for WRITE errors. Small mistakes.
    The only way I can think to explain this next part is with a visual. Quickly made but it should make sense. I hope.
    The track or Data written at slower speeds is thicker than a track burnt at faster speeds. This is not to scale.

    Each step up in speed is usually doubled. 2x, 4x, 8x,16x etc.
    So the track becomes half as wide for each step up in speed.
    And it is like in second image Fuzzier. It sounds weird but I couldn't think of any other way to describe it simply.
    An Audio CD burnt above 8x will skip when you hit a bump in your car. Where same CD burnt at 4x wont skip at all.
    This is caused by the Laser reader inside the Player to be either badly worn or dirty, and or the track just is too thin and any jolt will cause the laser to miss.
    The Laser reads through a Crystal used to focus the light finely enough too read the track. With use the Crystal breaks down slowly and the ability to focus a fine point becomes harder.
    So that fast burn at 16x or even 32x may work OK in your PC or home DVD player. In a Car it must also accommodate with movement. Good engineering fixes most issues that, but not everything.
    Now being that this .ISO image is actually an important piece of your cars navigation and usually also integrated into your cars modern Computer Control System.
    It is designed to allow for small occasional errors, not many. And the original Disc provided is a STAMPED not BURNT image. The only errors in them would also be the Master Image and every other of the batch.
    And that can be either remade or software can be used to control how the error is read.
    And with a burn at speed on a common PC is going to cause many different problems with that software.
    That is why some disc's work and some don't.
    But it is why it is Important to do as the Man keeps advising and burn it SLOW.
    Your cars Computer will then be easily fooled into accepting your COPY as an Original.
    And how to make an Audio CD for the car that won't skip.
    I have tried to explain this as easily as I can, I hope it helps some of you to understand why.
