Hello this method works for a DVD MK4 for a E65 7 SERIES 2001- 2008 ?

Hi, If your car is equipped with the same BMW Mk.4 navigation computer model, it should be the same installation process. 👍

Hi my navigation MK4 does not draw the CD. Will replacing the laser like in your video solve my problem?

[@straight_to_the_point7869]

If your Mk4 doesn't eject CD, try to press and hold eject button for 30 seconds, if that doesn't work try to reset navi head unit. If none of above works, there is a chance that CD loading mechanism is stuck or damaged and need replacement of whole CD mechanism which is described in this guide. Hope that helps.

Hi, do you know when the fan on the dvd module is kickin in? I looked at it today when i started the car and its not spinning, maybe when it gets too hot, I have no idea?

[@straight_to_the_point7869]

Hi, I don't know either, never checked this fan operation, but i think as with any other audio video equipment, there is possibility that it might turn on after the unit gets warm.

[@ivaylohristov6058]

Yeah I guess so. One more thing, I swapped the dvd mehanism with another one(different code) and its working fine. So maybe it doesnt matter the code if you are replacing the entire dvd mechanism but its a must to check the model of the laser if you are replacing only the laser inside. If we remove the dvd mehanism, they are all with the same boards and chips, I didnt find any difference. Did you find any?

[@straight_to_the_point7869]

@@ivaylohristov6058 Yes, with optical pick-up laser/lens i would only use exact correct part number, because there are differences in length and design of wiring and connection locations, therefore connection or wiring might not match. With the complete mechanism replacement i would be careful, mainly because some are used in Mk.3 and some Mk.4 Navi computers and there are some differences.

[@ivaylohristov6058]

Yes, I forgot to mention I am talking about only for MK4 complete mehanism swap that it doesnt matter. It only needs to be from another MK4 module.

Olá de Portugal! Tenho sistema BMW mk4 exatamente igual com unidade DVD drive M3 4.6. Poderei substituir a unidade (mecanismo apenas) pelo DVD drive M3.5? Obrigado desde já.

[@straight_to_the_point7869]

Olá, Se o seu mecanismo de DVD Mk.4 for Mk.3 4.6 eu aconselho você a substituir pelo mesmo Mk.3 4.6. Espero que ajude, desejo-lhe tudo de melhor.👍

@@straight_to_the_point7869 a unidade que tenho estava a trabalhar bem mas de um dia para o outro deixou de dar e começou a apresentar os erros que o senhor mostrou no seu vídeo... Entao retirei o CD e reparei que o mesmo estava com muito pó preto e parece que fiquei com a sensação de ter queimado algo há unidade mas não tem nenhum indício disso e decidi desmontar a unidade do mesmo modo que o senhor mostra para efetuar limpeza ao laser mas de nada serviu. Devo assumir que o problema será mesmo do laser? Desculpe o texto longo e obrigado desde já pela atenção. Grande abraço!

[@straight_to_the_point7869]

@@vitormachado9607 É difícil dizer, mas se o mecanismo de dvd aceitar e ejetar discos e você puder ouvir o disco girando dentro, pode ser apenas um laser defeituoso, mas não posso garantir isso. Espero que ajude.

[@vitormachado9607]

@@straight_to_the_point7869 sim ele aceita e ejeta bem os discos...e numa fase inicial dá para ouvir o disco girar e experimentei visualmente sem a tampa que logo que o disco é introduzido ele gira mas entretanto acaba logo por parar... Daí eu assumir que o laser poderá estar mesmo defeituoso... Primeiro a unidade informa que não tem disco inserido e depois dá me mensagem de erro na leitura do disco... Noto que acontece sequencialmente...

[@straight_to_the_point7869]

Pela sua descrição, realmente soa como uma lente de laser defeituosa, mas mais uma vez não posso garantir isso.
