According to my calculations 122Ω between ground @ 14.2V would give the following voltages.

Volume Down: 248Ω = 4.682V

Volume Up: 294Ω = 4.164V

Seek Down: 2370Ω = 0.695V

Seek Up: 1180Ω, 1.331 = 1.331V

If you get any free time with a multimeter, can you double check it and measure the voltage when the button is pressed and the car is running? Also, try to swap programming so physical seek buttons are using volume functions and vice versa. I was troubleshooting a Sony RM-X4S wired remote with the Unika and by altering the learning sequence, I found out that the "OFF" button forces the Unika to get out of programming mode. So, in order to fully utilize all 7 functions on the Unika, if I wanted to use the "OFF" button then it had to be the last one programmed.

:good:

According to the developer's wiki, "Car UI mode always on. User cannot manually switch the system mode."

With that in mind, I tried iHeart Radio on the Asteroid Smart. Apparently, there are two versions of the app; iHeart Radio - Internet Radio and iHeartRadio for Auto. I tried both of them and found kind of weird results.

The "iHeart Radio - Internet Radio" app worked fine on the Asteroid Smart. It is a little busy for a car interface but it works. I have a Unika SWC adapter and the Media Next button will switch to next station. I also have a Logitech Keyboard connected with a custom keylayout file to allow the HID media play-pause, prev, and next buttons to work. The USB HID signals for MEDIA NEXT and MEDIA PLAY-PAUSE will work with the iHeart Radio app. It does not respond to the MEDIA PREVIOUS button though.

However, the "iHeartRadio for Auto" didn't work for me. I suspect the root of the problem is that it is checking for a connected bluetooth device with car mode enabled, instead of the actual device it is running on. Unfortunately, I couldn't get my Nexus 4 into "Car Mode" since apparently, it doesn't have one. I even went as far as to install; Car Mode Ultra, Car Mode, and Car Mode Control and none of them would provide the car mode necessary to get iHeart Radio for Auto to work on the Asteroid. Even if it did, I would suspect it would try to play the music on the phone instead of the car speakers.

The last screenshots does show the Nexus 4 using the "iHeart Radio for Auto" app in tandem with the Asteroid Smart. The music is funneled through active bluetooth connection to the Asteroid BUT it is NOT played through the "iHeart Radio - Internet Radio" app. Instead you have to go into Parrot's Music App and select the Audio Source for your phone's Bluetooth. The on-screen Media Next and Previous buttons on the Asteroid will facilitate the rotation selection between the different stations on the Nexus, but I had to press the Media Play/Pause button to actually load them. It is kind of an awkward setup but I suppose that it will do in a pinch if you're not able to tether or connect the Asteroid to WiFi.

If you're looking for something a little more integrated, I suggest that you contact Clear Channel Broadcasting and/or Parrot to see if they can work something out. Parrot already has repackaged other internet streaming apps available in the Asteroid Market, like TuneIn, Orange LiveRadio, Spotify, etc, so they can be accessed as an audio source from their internal music app.
