What is CDC and SAT Firmware/Mode/Emulation?
CDC is CD Changer emulation. GROM Car Audio Kit emulates CD Changer, and you will use regular CD changer controls to change tracks/disks, control iPod/iPhone/iPad or Android phone. CDC emulation is available for select GROM compatible cars.
SAT (or XM) stands for Satellite /XM radio emulation. Usually available for cars within United States. If you connected iPod/iPhone/iPad, Android phone, USB stick to play, charge and control, you will use Satellite/ XM controls to control your device. Text will be displayed on SAT emulation compatible stereos. Stereo should be SAT/XM capable, but XM/SAT receiver has to be physically disconnected.
Check your product documentation to determine if your GROM uses CDC or SAT (XM) emulation.

How many files per root folder (playlist)?
We have tested with ~1000 files in a playlist. So technically no limits but be aware that it might take longer to switch between tracks and proper track ordering may not be possible.
What formats/bitrates it supports ?
What limits does GROM-USB3 have?
Can GROM-USB3 power up my portable HDD ?
Yes. It is able to provide steady 1A @ 5V which is enough for the most portable hard drives
How many tracks device support?
USB3 has been tested with ~10000 tracks on a drive (~80GB) with 20 playlists (root folders)
All supported stereos are not able to show the track number larger than 99. It is normal and will not affect the track currently playing. In case if you play track 1467, the stereo will show Track# 67

Should I name folders in certain way and place all files into the same folder ?
No. We do not recommend using 1 directory for all your files. It will make it hard to preserve the file sequence.
It is better to organize your music like: Playlist -> Artist -> Album as shown below
Folder '01-Mine' will be mapped to the first DISK and all files inside directory 'Extreme Behavior' will play in ascending order (01, 02, 03 etc) and will not mix up with any other album.

External audio player does not produce good sound through 3.5mm jack
On my radio MIX/RND mode will not allow to advance tracks in random order
This is stereo limitation. Turn the MIX/RND mode on and let the track advance in random order upon track completion
While in AUX mode I hear background noise and whine

Does bluetooth remember multiple devices? How does it auto connect to one when the car is turned on?
The GROM Bluetooth is capable of pairing up to only 2 devices at a time. It can only connect to one Paired device at a time. It will auto connect to the phone that is nearby when the vehicle is started.
The car came with Bluetooth phone capability but no streaming audio capability. If I hook up the GROM Bluetooth can I use it for the A2DP streaming only, and use the car Bluetooth for hands free calls?
If you have newer smartphone, you should be able to select which paired device will handle phone calls and which will handle music streaming. This is all typically done from the phone Bluetooth settings, and available in iPhone and Android phones.

The phone and GROM syncs at times and on other occasions it will not stream audio.
After first turning on stereo/GROM please give the GROM 10-15 seconds to fully sync with bluetooth before hitting play on device.
My phone is connected to GROM Bluetooth, but there is no sound coming from the speakers.
Make sure that the Bluetooth volume is turned on and all the way up.
Our cellphones are vital for keeping us connected, informed, and entertained anywhere we go. And thanks to modern, hands-free technology, they’ve also become an integral part of the process of getting there—especially when going by car.
Hands-free cellphone use in the car isn’t just a necessity, it’s now the law in many states. Fortunately, most phones today are equipped with easy-to-use Bluetooth technology, which can be turned on from the Settings menu to let you make calls, access map apps, and more without even touching your phone.
Bluetooth is a short-range wireless standard that uses radio waves to let multiple devices connect. To use it on the road, you will need to “pair” your car and phone together, which usually takes just a minute or two. Check your Owner’s Manual for specific instructions for your vehicle. Once you’ve paired your car with your phone’s Bluetooth, you can use voice controls through your in-car entertainment system to do things like make and answer calls, or use navigation software to get directions. If you have a vehicle without an entertainment system, you can pair your phone directly with a Bluetooth-compatible headset to make hands-free calls.
Many newer vehicles come with an option of integrating directly with your smartphone’s software, letting you control messaging, navigation and other apps using voice controls. Again, refer to your vehicle’s Owner’s Manual to confirm if these will work for you. Apple CarPlay lets iPhone users get turn-by-turn directions, make calls, send and receive text messages and listen to music or podcasts using the voice-activated Siri personal assistant, while icons are displayed on the vehicle’s interface that mirror the familiar features on your iPhone’s home screen.
Likewise, Android Auto uses Google Assistant to offer much of the same functionality for Android smartphone users. Apps and their audio content will run on the phone, but can be heard and controlled using the sound system of your car. Once Android Auto is installed, you’ll simply say “OK, Google” or press the voice control button on your steering wheel to begin using its features.
Don’t leave home without making connections to Bluetooth, Apple CarPlay, or Android Auto. Like a spare tire or jumper cables, they’re essential tools for keeping you safe on the road.
