Dongar PRO (Parking Mode Dash Cam Adapter) Development Updates

[SP4RUNNER]

Good to know. I will now wait till they fix the issue. Can’t stand high pitched noises.
What dash cam did you buy?

I purchased the REDTIGER Dash Cam Front Rear, 4K/2.5K Full HD Dash Model F7NP

I ended up installing it to see what it’s like. I still hear the whining on and off depending on background noise. Not ideal. I have an a229 with rear camera so I can’t imagine how much more draw it would need.

Im also noticing it doesn’t seem to trigger parking mode correctly. It just stays on….
Parking mode is correctly set but it never switches or announces parking mode. I left my truck for a couple of hours and when I checked I just had back to back videos.

Reset the settings and same same. The a229 also announces when it switches to parking mode and it doesn’t anymore. Worked fine in my last vehicle with the normal hardwire kit.

Anyone else have this setup? Wondering if I’m missing something. Checked online for a while to no avail.

@RigidYota thanks for the feedback re: the whine... I promise we'll get it fixed, we ordered the components and getting the PCBAs made asap. It was just not something we expected because it's very current dependent and we focused all our testing on high power. Just curious if you tried plugging in something like an iPhone cable in and if it goes away?

Re: Viofo, I found some threads of people having similar issues with the camera but confirm parking mode can activate on other constant-power source with 5 minutes of inactivity. The manufacturer is implying that it is extremely sensitive though. It might be Viofo's way of getting you to use their hardwire kits instead of the many alternatives of the market, but I'll look into it and see if I can figure out if they're doing something proprietary and add it to the next version.
