I have just got off the bay of flee a 2010-2011 Navteq sat nav disc it is new and unused but the upgrade disc you use first before you use the map disc is a copy on a sony 700mb CD-R. My question is this do i use this disc or will it damage the head unit as i have read that they can damage the unit. Any idea's please. ???

Struggling to see why you would accept a counterfeit software disc as being new and unused. How do you know? Its a blatant fake, how can you trust what you have been told by the seller? How can you know what it will do to your head unit?
Send it back, report the seller for fake goods, get a refund and then buy a genuine disc from a trusted source.

The map disc is genuine and i have sent an e-mail to the sender. It said in the advert on the auction that the disc was new and unused and that is the case for the map disc but not the upgrade disc. Got the disc for a good price (map Disc) but as said the other one they have done a copy and sent that.
I take it you only have to use the first disc once and then keep the map disc in as i do with the one i have in the unit at the moment, so i take it i just need to use a genuine update disc.
I am thinking of sending it all back as you say
-
I don`t think it would be fair to the owners of this forum if you discussed any illegal or counterfeit software here any further.

Thanks dave i am going to report to the bay and send the
crap disc back Admin please lock

I think what has happened is this..
These disks are supplied as a set, for all of europe.
Most people only want 1 of the disks, so sell the rest separately.
Now theres only 1 update disk in the set, so he is supplying a copy of that to each purchaser, along with the original map disk he doesnt want.
Personally, id use the update, 1 read from a homemade cd is probably not going to do a world of harm. then use the maps.

Cannot disagree more !!
Unlike reading from a CD, where any bad read or poor data will simply mean that you get an error message, or cannot find your destination, if you use a disc to actually reprogram a head unit, any such loss of data could cause massive harm and corrupt the head unit to a level from which it cannot be recovered. I`m finding this a lot on the Audi forums at the moment, where everybody is obsessed with running the latest version of software on a head unit it was not designed for, and you only need one byte of corrupted data to shut down a head unit.
Although you shouldn`t really use copied discs for data, you must only ever upgrade firmware with genuine discs

:o Have the designers never heard of error checking? CRCs? Yeesh.

You would hope so, given that a genuine CD will be far from error free. Then again, I can imagine that the update might be in several parts, rather than one big file that gets loaded, error checked and then flashed. If that's the case, and it finds a corrupted file half way through the process, the end result might well be an expensive brick.
I'm always surprised how fragile firmware update code is for a range of devices. Given that it's about the only area where you can't unbrick a device in the field by releasing another update, you'd have thought developers would make it robust. I guess they're just constantly under pressure from their managers to implement shiny stuff as a higher priority. ::)
-
Hmm.. true enough - thinking about the products I've worked with here, shiny stuff does always seem to be a priority :-\
Still, at least these devices are updateable, unlike some of the ASICs I've worked with that have lovely burned-in bugs ;D

Oh, gawd! Don't get me started on that. Reminds me of a previous life when I was trying to work around such issues in software and, when that didn't work, by bodging on other bits of hardware. ::) The customer didn't bother to check all the functionality in their ASIC before the warranty ran out.(http://dl.dropbox.com/u/26795734/Smilies/shitsfan.gif)

In this instance, we are not talking about the error checking on a manufacturer pressed disc, we are talking about how well some scrote has ripped it to a disc in his bedroom using his personal computer - I would expect far more errors !!

True, but in an ideal world that still shouldn't cause a bricked unit ;) If it does, I'd still argue the unit was designed badly in the first place..
Of course we already know the NCDCs aren't exactly top drawer :)

Disagree, the units work well enough, its only the constant obsession with upgrading the firmware that always causes the problems. These have all been working fine for the last 15+ years, not sure what the current trend of changing the operating system is supposed to achieve.
If you tried to upload a new operating system to a computer and switched off half way through, you would find in 99% of the cases that the computer was FUBAR as the BIOS would be so heavily confused that the thing would no longer power up. Its the same thing on the radios - corrupted data can screw them up also, and nothing to do with the way they were designed.
-
I think we'll have to respectfully agree to disagree, there, then :) There's a big difference between installing an OS (thousands of small files) and a firmware (a few small files which should all be pushed as a monolithic block, ideally with secondary backup PROMs that aren't overwritten until the primary PROM is confirmed updated and CRC checked)..

My problem with the OP is not what is being uploaded, its the poor quality and non-genuine media it is being uploaded from
;)

Well that won't help I suppose.. but CRCs should protect against that, done properly..
Then again.. when is software ever done properly? ;D
Hopefully the OP will find a set of genuine discs :y

Fear not, the update disk is NOT required on NCDx range, despite the fact Navteq (erroneously) say it is.
The software update for NCDx, if required (depends how old your previous disk is, but it hasn't been updated since around 2006), is on the map CD. V8.something iirc.
Also, despite what Navteq claim, you *CAN* go back to previous disks with NCDx systems.
The update disk is for other systems.

Thank's all I have had an e-mail back from the sender who said i had paid him for the map disc only and the other disc he sent was FREE. Will try the genuine map disc out :y

Sounds like you bought yours from the same chap as I did - ebay.de perchance?

correct
