The Grom does not have an external mic.
I believe it uses factory mic as I’ve taken calls via wireless CarPlay. And I never installed a mic. And one of the updates was an auto mic gain adjustment which seems to adjust it well as I haven’t gotten any complaints from the calls I take.
Doesn’t mess with reverse camera. Auto front camera works normal. Reverse and overhead also.
Also has ability to add a camera which is what I will do for my trailer rear view camera.
Climate you have to push a few buttons to get to the OEM controls. But no issues except annoying.
Can’t bypass Grom to just start up in OEM
mode. If that’s super important to you mount it in an accessible place and unplug the cable when taking it to service. Mine it zip tied to the underside of the pass foot well. I have easy access for usb and HDMI. I haven’t tried this method but the piggyback cables should just allow OEM to function but I’m guessing here.
I sound like I work for them but I don’t. It just works and they are adapting as we go which is huge.
Downsides
It runs an older android OS. I think 8.
A lot of apps you have to get the legacy apk
The occasional drop out but seems like this is industry standard. Even for OEM integrated setups.
Can’t get some apps to work like pedal Commander.
Currently I’m having issues with the hdmi to mirror in the rear screens but I have a daily email back and forth with Grom about trouble shooting. Current suggestion is to open unit and check the ribbon cable which I’m comfortable doing. They said I could send it to them and they could test it if needed.
The tech literally made a video on how to check the cable and posted it on youtube for me just now....I mean come on...that's insane
