I'm looking for dwd to write at 2x..

R-T-B · May 19, 2019

So find some media that supports 2x?

I think ford is right. It's the media, not the drive.

Good luck with that. I say just burn it at what ever speed you can

read first post.I already burned at 4x and is not ok.4x speed is not ok for my nav units car.With 4x my nav sometime blocked and become laggy.Manufacturer recommend 2x or even 1x for my version of car.
case closed.

Can you provide a link to where you got whatever you're trying to do?

2006 isn't that old.
Most updates are done via USB as per flmatter's link: https://www.bmw.com/en/footer/software-updates.html
If you're trying to update more than that, it gets super complicated:

I don't know what you're downloading, how you're trying to run it, or anything.

If my understanding is correct, you'd put the DVD in the head unit, it would read it, verify CRC (cyclic redundancy check), install, and reboot into the new firmware. The DVD is then removed. I'm assuming you did these steps...

You say "nav sometimes blocked and become laggy" with the DVD no longer being used, correct? Then the firmware it installed in your head unit is apparently incompatible with the head unit causing these issues. It has nothing to do with the DVD. You're probably best off trying to find a different version (probably older) and trying that.

Read speed and errors... man that sounds like some proper early CD-ROM era fairy tale, like speeding up your PC with extra virtual RAM via 'this website'. I've never ever seen that occur in any practical use case. The write speed wasn't the issue, the issue was your buffer ran out faster and PC couldn't keep up. Or that you would be doing something else in the meantime to create a similar effect. I remember how 'its burning a disc' was actually saying 'keep your hands off that PC'.

Try DVD-RW disc, they're always lower speed than regular DVD-R's.

Or just use your phone for nav, just like most of the people do. At least that way you'll have fairly up-to-date maps.

not the disc is the problem,my unit is the problem because don't allow me under 4x.
a disc as it is written at a lower speed, the quality of the writing is more durable and more qualitative, and you have no problems with that disc in any reading unit.

That's not true. The manufacturer and dye deturmans the durability of the disk. Verbatim or Ridata are about the best
