IX1239BHL (10.25', Unisoc Tiger T618 8/128 Gb) on E39 Expirience - azlarbek@gmail.com - 11.08.2025
Traditionally, I want to start with thanks to the brilliant developers and the entire team of I-Bus App.
Car: BMW 523iA (1999 export for Jpn);
HU: XTrons IX1239BHL;
Interface: Resler USB I-BUS module.
Description: Installation made by local specialist regarding to included documentation (thus ACC still wired through CAN Box, Recommended to reconnect to HU) with 1) Fittings for radio in BMW E39 (p/n: Halter02), 2) 3x WAGO terminal through connector (p/n: WAGO01) - really recommend to use it.
Issues:
1. HU never turns off while ignition is 0 (goes to sleep) - there is solution in WiKi for it.
2. Built-In 3/4G modem loosing connection and giving an error message ("...modem assert in file drv_common_iram.c...") after waking (after sleep mode) if default launcher is changed. With stock Launchers there is no issue.
3. In I-Bus App hanging of additional light (Front fog-light) to turn signal while selected exact speed limitation for this option. When no limit - works perfect.
4. I-Bus App successfully connecting to the Resler USB I-BUS module when HU starts, but hanging in half a minute after. Going to Settings->General and selecting USB Module again (it is displayed there already selected, anyway select it again) solving issue totally till the next start of HU.
P.S. Made a Background for BC with my settings, maybe it will be usefull for other users aswell: Display - 1920x720; BC layout - Wide; BC fields (TT/LL/RR) - 00/30/00; Fonts - Big; Fonts for tinny items - Big.
