I have made an update maps in 2020 if I remember for my Avic F860 BT with your help.via ebay.Then I put the TeleAtlas mapow I would like to change them again on the same device with new ones(TeleAtlas/TomTom better).
I provided all the information I had.
We don't have these models in our country. And I don't have any experience in repairing them.
I need a working radio to dump the firmware from it.
But I don't have access to them.
на карту после установки в ГУ устанавливается пароль
что бы она читалась на PC нужно ее распаролить.
некоторые карты не работают. например некоторые модели Smartbuy
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.
