Hi
My MK4 went on the fritz (Please wait...) about 8 months ago. I recently opened it up, changed the laser unit. But still same problem- when I insert the DVD- it didn't spin much, and just stop. Got new disc from NavteQ- same thing.
Opened it up again, and cleaned the rails. Same thing.
Opened it up again and spun everything, took it APART, wiggled everything around. WORKS!!!! with new disc too!!!!

Now I need to upgrade the version. I have 4-1/12 the first version of MK4.
I got a disc on ebay paid money $ (I know, stupid). It's a CD- I put it in and doesn't really do anything, spins a little and just stops. So I think it's because it's a CD- So I burn an image to DVD using MagicISO Mode 2 and everything. I put it in and it keeps rebooting the nav screen- BMW logo..spins, and then stops and then spins again and BMW logo again- over and over again.

No software update screen at all.

Please help. I've almost got this old thing fixed, jus t need to update the version.

Any ideas?
