So, I have some new info...
To answer to HJB regarding the versions of the two units from under the joysticks on the bottom right off the front: My friend's MMCS and mine are C-01.
For any other info concerning SW, CDDB or nav versions, I think all the details for MY MMCS are in the fives picture I attached in thread #1. Unfortunately, for my friend's MMCS, I do not have any details as his MMCS doesn't work anymore and I couldn't catch them before bugs (only that also C Crosser of 2009 and with European version)...
Concerning depowering battery during at least 30 min:
- My MMCS: Test done. Nothing changed after this except that I lost all radio stations in memory and that I do not see anymore "bonjour" and "au revoir" when switch power on and off but "Hello" and "Good bye". But message "It's difficult to read the hard disk. Please wait for a while during hard disk is restored" appears after power on, and then disappears after 2 minutes. Please note that I removed since 3 days my HDD from the car and that in this case, this is error message stays constantly when the HDD was not in.
- My friend's MMCS: I just tested to depower battery, removed the HDD, wait for 50 minutes, repowered battery, put the HDD again, and now... A new error message never seen in my car nor in my friend's car... "Insert disk program". and nothing else... If I get out the HDD and put it again: same message. Please note that before this test, his HDD - in my car or in his car - always displayed the same error message than mine while the HDD was in: "It's difficult to read the hard disk. Please wait for a while during hard disk is restored". And I do not see anymore "bonjour" and "au revoir" when switch power on and off but "Hello" and "Good bye".
As a reminder, the only thing I made after I got for the first time my error message with my MMCS is try to read the HDD to a computer with a IDE 2,5 cable to USB. Not working as I wasn't aware I had to unlock. Then put the HDD of my friend in my car => I was able to update timezone. I tried to read his HDD with the same IDE 2,5 cable to USB to a computer thinking that my HDD was broken and that I would be able to clone/copy his HDD. Not working as I wasn't still not aware that I had to unlock it. Then I put his HDD back in his car and in my car: Error message with "it's difficult blabla"... Nothing more. And my HDD works now in my car but with the error message "it's difficult blabla" during two minutes and after this, all is ok (but wasn't working at all during one month before ANY TESTS) and if I put my HDD in his car, the error message "It's difficult blabla" is displaying constantly.
I read again the great post with 59 pages and found on page 30 a post with Aalisant who also had an error message "Please insert disk program":
How to unlock MMCS
Result of his analysis and resolution of his problem:
« So after one week of nightmares I have solved the problems!
First my fu** adapter ide 2.5 to 3.5 was broken and the result 3 HD burned also the toshiba 30GB original. »
==> Do you think the IDE 2,5 cable to USB I used with the two original Toshiba HDDs could be defective and cause damages to the two HDDs??? Even if mine is working again with message error during two minutes in my car and no more when I insert it in his car.
If such, I really hope that I will be able to copy/clone the data and the HDDs because not done before all this happens and now two cars with non good working-MMCS...
Tomorrow I will try to get a copy/clone of the two HDDs.
Thank you very much for your analysis and if I could get some advices re my questions in the message posted yesterday
