Default Radio AUX input not loud enough

I have a Road Tech 665, connected to StreetGlide 2012 with the NIM card and AUX for XM.

When I run just FM or AM the sound coming from the speakers is just fine at any speed.

the GPS and Radio is working correctly, when there are GPS commands the music cuts out, whether it be AM/FM/XM just fine. However I can't hear the commands above 55-60 MPH.. ie.. sound isnt loud enough

Its the same with XM feed through AUX. if I am listening to XM works great, however when I start getting good wind/road noise it drowns out XM, but not FM or AM. So the radio can play loud enough, but the RoadTech 665 cant get the speakers to be loud enough

I have the GPS sound settings set at 100% for commands and media. I can't find any ACV setting for AUX input but i have it set as high as I can on FM/AM just to see if in impacts the input from 665.

The harley dealer tells me I need to put higher quality speakers in the batwing. Thats kind of silly, since FM and AM are loud enough even up to 100mph with massive road noise.

So, its not the speaker or the radio. So it has to be the AUX input or the GPS.

Anyone have any thoughts?

This has been well covered on the forums. It is generally agreed that the AUX input is at a lower volume than the radio and CD. This is a design characteristic of the head unit itself.

Solution is to use an inline booster, such as the Boostaroo to increase the volume of the signal going into the AUX jack.

all you could do is some kind of line amplifier between the gps and the aux in.



I use the aux in for my xm and ipod- plenty of level- equal to the am/fm/ cd levels- both my ipod and the XM have level controls to the aux, neither of which are at 100%.

All well and good.... but, he said he has the NIM. And lower volume is the nature of the NIM. Better than stock speakers will help a little though. They will not make it louder, but it will become a little clearer.

I run my AVC at 3. AVC is universal on AM/FM/WB, and AUX

One little trick...... use one of the female voices. They seem to be easier to understand. Or maybe it's the NAG factor

Is the 3.5mm cord that you are using for the AUX input a Stereo cable or regular 3.5 cable. This made a big difference with my iPod

When the voice commands start, the HK radio switches over and displays "phone" on the LCD screen. This is the time that you have to increase the volume. As soon as the NIM cuts out again you will have no control over the volume of the voice commands. Give it a try.
PS re-read the question again and found that my answer may not be relevant but, I can't delete it.

You're right..... I forgot about that (Damn winter makes my brain go dead)

When the GPS starts to speak, tap your handlebar volume control. It may take a few tries to get it where you like it.

Can't help with XM... I have a 660
