Vanessarino, after you confirm that the GROM is installed correctly and is getting power, try turning off the radio, unplugging the GROM, plug it back in, and power up the radio. Unplugging and plugging the GROM resets it. If this doesn't work then contact GROM tech support http://www.gromaudio.com/support.html as they respond quickly with good procedures. I've had a couple issues which they helped me resolve.

 

Yes i bought the bluetooth add on.
Which is the right wire to tap? I did it on the yellow wire which was part of the cables diagonally attached to the grom cables.

 

i dont remember the color to tap for power. can you confirm you are getting power to the unit? does the usb stick led light up? or usb cable?

 

I'm pretty sure it's the yellow wire. I just checked the FSM and it notes the yellow wire.

 

I don't have a usb stick but I tried plugging my phone through the iphone cable and it doesn't charge.

 

if your iphone isn't charging.. your grom probably isnt getting power..

take the plastic cover off the grom unit. if your car/audio is on, there should be a red LED light that stays on. if it's not on, it's not getting power.

 

I'm going to guess there's no power, so you may have a bad connection or the wrong wire. Redo your wire tap to make sure you have a good connection and if there's any doubt check it with a multimeter or circuit tester.

 

double check you are tapping the correct power wire for your year model. idk if it varied from 04 to the 05-07 editions

 

I am planning on buying one of these:

I just had some questions, Do you need the AAlinq app to play music from your android phone through USB or bluetooth? is there a big difference in audio quality between USB and Bluetooth? Do you need the app for steering wheel controls?
Lastly do the steering wheel controls work with USB flash drive plugged in?

Thanks

 

GROM works pretty well with the steering wheel controls.

the difference in quality of BT and wired is measurable.

BT is like 1000 times more convenient, but it feels like i am listening to 96kbps/128kbps MP3's... which isn't bad.

Wired setup feels like 192kbps+.. the bass and voices sound more clear

 

Thanks I went and bought the Grom USB3

 

Drifter2090, the USB3 should be a good choice as it has all the options. When I first installed my USB2 there was a measurable audio quality reduction with BT which became even more apparent after I upgraded the the amps and speakers. I wouldn't worry about it if you prefer convenience over quality, as I still find I use the BT from time to time, but if you're an audiophile you'll notice it.

I find the BT is like low bitrate encoding, and there are key components of the sound missing or modified. The low frequencies are reduced, vocals and upper mid range are reduced in clarity, and there is an echo effect with certain frequencies. The USB flash drive can be equal or even better than CD with a high bitrate encoding. The aux input is as good as the phone, mp3 player or whatever source you've connected can reproduce, not quite as good as the USB but pretty good. AAlinq is good but there are definitely missing components in the sound so not sure if that's due to the app. I haven't heard the Android streaming on a USB3 unit or iPhone on my USB2.

 

Thanks for all the help man! Yeah I care a lot about audio quality I didn't even order the additional Bluetooth piece. Also update your USB2 firmware here:

http://www.gromaudio.com/software-usb2.html

"USB Audio streaming with control supported for USB2P" it will let you use steering wheel controls while USB streaming w/o the AALINQ app.

 

The actual A2DP bluetooth streaming audio protocol *shouldn't* be a limiting factor, it's more about what sort of compression over the a2dp stream your device is using. http://soundexpert.org/news/-/blogs/...o-quality-a2dp

 

I have a USB2 not a USB2P, as I bought it over 3 years ago now. It can' t do USB audio stream, it can only do it with AAlinq. I'll be curious to hear your impressions of the USB audio stream once you get it setup. I probably won't buy a new unit for this car anytime soon, but would consider it for another car.
