  1. your problem is with the radio power supply when the engine starts, the voltage drops to a minimum level and the radio reboots can be solved by installing an additional condenser.
  2. after inserting the SD card into the radio, a password is set on it. The SD card will not be read by WInodows. in the disk manager you will see a RAW partition. you won't be able to format it.
  3. if you cannot enter commands, then you have a problem connecting the TX wire from the USB TTL adapter you also have an unstable RX connection I see artifacts in your log
  4. you have 3 seconds to get to the uBoot console. after turning on the radio, you need to press any button on the keyboard. the console will become available. if within 10 or 15 seconds you do not enter any command, the radio will reboot into normal mode. in your case "easyrecovery" in the console, enter the command "warp" the radio will reboot.
  5. this model uses eMMC chip IC7691 in the second photo unfortunately there is no solution to this problem in Pioneer service documents
  6. This problem is for models DMH-160BT,DMH-1700NEX,DMH-1770NEX,DMH-A4450BT,DMH-A4480BT,SPH-DA160DAB I have a service bulletin for SPH-DA160DAB the repair process consists of 2 parts 1. soldering 2. Update FW I have files only for SPH-DA160 NO WARRANTY THAT THE FIRMWARE FILES WILL WORK WITH DMH-1700NEX,DMH-1770NEX Bulletin Nr. 1918
  7. this is a manufacturing defect. bad soldering flash ROM (U27) repair will require a soldering station and force firmware rewrite I can provide detailed information on how to fix the defect. but you will need to be able to use the soldering station
  8. downgrade firmware 1.14 in the Debug menu, you can set the time manually
  9. no there are hardware differences between x000 and x100
  10. Pioneer apps are the same in 1.04 and 1.06 Perhaps there are differences in the system libraries. but that would take a lot of time to check. unfortunately there is no change log
  11. No This is the same 8400/8500/8600 only software difference +weblink only
  12. There are at least 3 different versions with tuners NA: radio (200Mhz step) + HD radio (built-in tuner) + SiriusXM tuner (external) EU5: radio (step 50/100 MHz) + DAB tuner (built-in tuner) UR\ASIA\BR\AU: Radio (50/100 MHz step) For all versions of AVIC, a 2nd radio tuner is available, which is used in navigation for TMC (traffic) PS version AVH-Z9x00DAB(EU5) was also sold in AU region. there are also 3 versions with iDataLink(CanBus) port only available in NA*\EU5**\UR*** regions.
