Repair of a BMW Mark IV Navigation DVD device - pete_c - 26.02.2020 Purchased a used Mark IV Navigation DVD device which needed repair for $70 USD. This is to upgrade my E46 Mark III. Testing it on my E83 which has a Mark IV Navigation DVD device. Description of device purchased. ...always comes up as cannot read cd/dvd, or error in reading cd/dvd, it may just need a cleaning, I installed the v32 software and it had no problem with the software cd... Swapped my E83 Mark IV for this device. Did an upgrade of firmware (V32) from a CD. Worked. Inserted my DVD NAV disk and device cannot read my DVD. Inserted a DVD head cleaner. Tried again with no luck. Took MarkIV apart, removed DVD drive and cleaned the heads again. Still did not work reading a DVD ROM. Found a source in China for a replacement DVD ROM drive. Description: DVD M3.5 Drive Loader Mechanism Fit for DVD-M3.5 of the RNS510 HighQ Price: $37.99 Guessing that the new drive will correct my issues. Here are some pictures showing replacement of DVD Drive. Hardware tools required: 1 - DIN removal tool to remove DVD drive. 2 - small flat head screw driver 3 - small torx bit size = T8 Steps to remove cover 1 - insert the flat head screwdriver in the spaces between the cover and the base on the sides of the cover plate and twist a bit and pull up on the cover 2 - remove cover from back to front pulling the cover up Steps to replace DVD drive 1 - remove 4 torx screws - these are very small. Be careful not to drop the screws. 2 - Lift the DVD drive up and disconnect the ribbon cable and flat 8 wire cable from the main DVD drive board. NOTE: pin 1 (one) is marked on the 8 wire cable. For the ribbon clip pull it out a bit and the ribbon cable comes out. Be gentle with it. 3 - put DVD drive back in case and install the 4 torx screws 4 - put the cover on the case. Testing the DVD MK IV functions here using my E83 to test. 1 - key off, press DVD eject button to remove DVD on existing MKIV 2 - using two DIN tools insert the tool on both sides of the DVD 3 - slide out the DVD Navigation unit 4 - remove both plugs (one is blue and one is dark brown) 5 - install cables in to fixed Navigation MKIV drive 6 - slide it in but do not lock it in place yet 7 - install navigation DVD 8 - turn key to on position 9 - see DVD maps fine. Also see DSP / TV on main menu here as MKIV came from an E46 with DSP and TV. 10 - downgraded to V.29 firmware then upgraded to V.32 firmware. 11 - will let it run for a bit on E83 before swapping the E46 MKIII for this MKIV. (E46 is in storage - well in garage covered right now). 12 - Total cost of upgrade here was $70 USD + $40 USD = ~$110 USD. |
