Sat Nav Fault - Help Needed
Hello Folks,
Grateful for help with the following fault on the Sat Nav on my XC90 (Oct 2011). I believe the Sat Nav is the RTI MMM+ HDD system that comprises the screen that rises from the dashboard and a box under the front passenger seat that contains a DVD drive, a 40Gb hard disk and some circuit boards. I recently had the vehicle's battery changed and then updated the mapping software. All went well and the Sat Nav was used on a number of long and short drives. A few weeks later the following fault appeared: - The Sat Nav turns on as normal and the screen rises from the dashboard. - The Sat Nav offers the options of booting in Simple or Advanced modes. - Regardless of which option I select, about 15 secs later the screen displays the following message, 'Unable to access the hard disk. Please wait...' - This is accompanied by a repetitive clicking sound from the box under the front passenger seat. - The message and the clicking sound continue until the car is turned off at which point the screen sinks back into the dashboard. - I am not sure if the clicking is coming from the hard disk or DVD drive. I have tried resetting the fuse that powers the system and removing and re-seating the cables at the back of the box under the passenger seat but to no avail. A Volvo main dealer conducted a diagnostic check and told me that the 'hard disk is corrupt' and that they would replace the whole unit for £1250. I have taken the box apart and cleaned the DVD lens but that did not work. I am also wondering whether I can replace the hard disk and what would be needed to reprogram it. Is anyone able to suggest a fix for this problem? Thanks in advance. |

I dont have one of those units, but the clicking sounds like a failed hard drive. Is it possible to swap the HDD out in the nav unit?

I can swap the hard disk but do not know how to reformat / initialise it. does this need specialist Volvo tools and software?

You're in a really interesting position! I've always wanted to back up my hard drive and replace it with an industrial SSD.
Since you're technically inclined would you be open to trying a few experiments to get it going? Swiss and I have done some reverse engineering of the satnav. I've started down the path of reverse engineering the firmware using SEGA Dreamcast SH-4 processor tools. BMW uses the same 2.5" PATA IDE drives in their late model iDrive units (you'd be surprised how many cars today still use 2.5" PATA drives): https://www.e90post.com/forums/showthread.php?t=1426773 Since their system loads a lot more from the drive (and stores music to the drive) there is an incentive to upgrade. People have found combinations of drives that work best at emulating old mechanical PATA 2.5" drives. Some SATA to PATA converts do not perfectly emulate old mechanical drives while others work perfect and lead to near instant load times. You're in the perfect position to try installing a new PATA 2.5" SSD and see if using DISC1 reinstalls the map data onto the HDD. I've also heard of a menu that forces a re-install of the map data onto the HDD via the RTI screen. Since you have nothing to lose, are you willing to try ordering a PATA ssd from amazon? Worst case you just return it.

From what I can tell so far, the MMM+ boots of flash first then loads off of the HDD (why your RTI screen still pops up).
Worst case if there isn't some way to initialize the hdd via a RTI debug menu or VIDA, someone can image their own HDD and that can serve as a way for others to restore their hard drives in the future. BMW owners have done this with notes what files need to be modified (serial numbers, etc) to overcome a failed CIC drive. I'd be interested in trying to restore your old HDD too if you get back up and running. Swiss might also be interested in seeing the contents of your broken drive / trying to recover + image it.

I agree with a failled hard drive scenario
To confirm, boot the nav into diagnostic mode and see what it shows. I believe it will go into diagnostic mode with a failed hard drive, but you need to check it Diagnostic mode will allow you to see what is wrong, but the solution does not change: 1. Volvo solution: replace nav 2. Home made solution: replace harddrive (and deal with the software loading issues...)

And if you don't know how, here's how to get the nav into diagnostic mode:
From a cold start (vehicle closed and locked for at least 15min, all gone to sleep, no interior lights on) 1. Open car, insert key and turn to PosI 2. Press ENTER, BACK, ENTER, BACK repeatably during the nav boot up sequence until the screen has risen and a Diagnosis menu is displayed. 3. Go through the diagnostic menus, observing all errors and taking photos of anything noteworthy Video: https://www.youtube.com/watch?v=FJTVIfUCdO8&t=14s

GenericVolvoDriver & SwissXC90, thank you both for your informative and very helpful replies.
I have been into the Sat Nav diagnostic menu and been through every screen available. The following are what I think could be relevant observations: 1. Image '0 Diagnosis' shows my top level menu. 2. Image The '2_1 Circuit Check' shows 'OK' against everything except the DVD-ROM against which there is a blank status and the HDD against which it shows 'NG'. I do not know what 'NG' means. 3. Image '3_7 HDD Info 2' could point to the potential to resent the maps / HDD. It has options for 'Map Update', 'HDD Update' and 'Key Disc' but I do not know exactly what these will do. 4. Image '4 Diagnosis Record' show my diagnosis options and is reached by selection option 4 from the '0 Diagnosis' menu. 5. Image '4_1 Diagnostic 2', reached by selecting option 4.1 from the menu at point 4 above. It shows 'DTC 5020: HDD Read Error' and DTC 5010: HDD init(ATA)'. I do not know exactly wha these mean. 6. Image '4_2 DVD Mecha Error Status 1', reach by selecting option 4.1 from the menu at point 4 above, shows data I do not understand. There are two more screen 2/3 and 3/3 that show similar data. 7. Image '4_3 HDD Error Status 1', reach by selecting option 4.1 from the menu at point 4 above, shows data that appears to indicate HDD faults but I do not understand it. There are five more screens with similar data. As a clarification of my initial email, I know there is a clicking sound from within the RTI MMM+ box/unit but I do not yet know whether it is coming from the HDD or DVD drive. Next Steps - Is it possible to use the diagnostic menu to attempt to reinitialise the HDD? If so, is it sensible to do so? - If the above fails then I am willing to replace the HDD and take it from there. All help greatly appreciated.

Well done, you posted exactly the right information
2.1 Circuit Check: HDD NG means No Good (or Not Good) 3.7 HDD Information: Do NOT select anything here as your hard disc is failing. You may end up in a non-recoverable state if you select anything 4.3 Error Status (1/6) is absolutely confirming a hard drive failure. The ATA controller is logging init errors. And the other screen is showing HDD read errrors. So your HDD is definitely bad. I do not know for certain, but I believe the nav coding is held in flash memory, and not on the HDD This means there is a good chance that you can fix your nav by fitting an HDD from a donor nav of the same part number You cannot just fit a 2nd hand nav unit is the nav unit is coded to the car. But swapping out the HDD from a donor nav could very likely work. Of course, you will have whatever maps are fitted to the donor nav. But you can upgrade them later.
