Due to the growing number of supported cars, program numbers have exceeded 999. In order to maintain one number format, we are moving from 3 digits, to 4 digits program numbers.<br/>In new LV-CAN200/ALL-CAN300 firmware (from 2017-09-01) all program numbers that were up to 999 are changed to start from 1000. So that further program numbers would continue the counting with 4 digit numbers.<br/>However, all existing program numbers stays the same, it is just "1" appeared in front of them. Device still understands entered 3 digit program number (via SMS/GPRS), it will automatically add "1" before it. If you enter "247" - device will turn it into the "1247". In Bootloader it is only 4 digit format available, just add "1" in from of the needed program number.
