Hello everyone,
I recently bought a Viofo HK3 HWK for my A119 v2, as my previous HWK had started malfunctioning. I know the HK3 is designed for the A119 v3 and A129 series, but I bought it anyway as it features both a mini USB port and a configurable low voltage cut-off (very important as the default 11,6V for most HWKs is way too low), and because I'd probably upgrade to an A129 should my A119 v2 die one day.
The HK3 comes with a separate yellow ACC wire for automatic switching to parking mode, but that kind of HWK-switched parking mode obviously isn't supported by my A119 v2. I first tried to only connect the red battery wire, but that automatically triggers the parking mode and my A119 simply wouldn't go on. No problem I thought, I'll feed both the battery and ACC wire at the same time... works like a charm at first sight, but then I discovered the low voltage cut-off is ignored when the ACC wire is powered.
Any ideas to get this working anyway? Is there a way for the A119 v2 to operate anyway despite the HWK being in parking mode, or how could I get the low voltage cut-off working despite the ACC wire being powered?
As a potential workaround, I thought of using a diode to lower the actual voltage by some 0.6 V off... but will the usual 11.6 V cut-off still kick in or will even that be ignored when the ACC wire is powered?
