MK3 to MK4 Upgrade by replacing DVD unit
I read through the laser repair DIY (http://www.xoutpost.com/articles/all...-nav-unit.html) and am planning to use it to fix my dead laser on an mk3 unit in my 2002 M3.
I was wondering if it would be possible to upgrade my MK3 to an MK4 by just replacing the DVD drive inside with an MK4 version (PN 65 83 9 241 764). This is the DVD-M3-4.6 drive. Would this work or are there other differences between the MK3 and MK4 other than the DVD drive itself? Thanks. |

Different hardware and different software. |
Got it, thanks :)
Do you know if I could use the DVD drive in an MK3 at all? Seems that it may not be possible to replace just the CD drive in an MK3 unit. Even if I can't upgrade it to MK4 just by swapping drives my laser is busted so I'd at least like to get my MK3 unit working again. |
No. It is impossible to use the DVD drive in an MK3 at all.
I recommend to buy a MK4 unit at e**y. You will love it. The difference to MK3 is big. |

Thanks, I looked into my upgrade options and personally don't think spending the money to get an entire MK4 system (excluding the screen) is worth it. For $100 I would do it but most of the used ones I see for sale people are asking $500-600 for what amounts to a 10 year old navigation system. For $875 I can get a Dynavin Android which is far superior to an MK4 system and will still maintain the OEM look.

It has a mickey mouse GUI that looks like a 4 year old using crayon's has been let loose on it. Sure it looks good on paper, but the actual item is utter rubbish. |
To be honest;
I did a swap for 2 weeks ago. I found a MKIV unit for € 250. I did a recode with navcoder, while it was coded for a E46 arrow screen. And this weekend I have sold my MKIII for € 150. So effictivaly I have spend € 100 for this upgrade. New firmware and NAV charts loaded and now all is up to date. |
