    Wow that looks great, can't believe I haven't found it myself in my quest to seek out an FM dongle for android. Believe me I have searched high and low! Guess their SEO isn't that great or it hasn't found it's legs on google yet. Anyway couple of things, firstly I can't see if it can be powered externally. It has a micro usb, but haven't found a datasheet or anything that explains the device in detail. Second, I'm not sure if the signal would be that great. In their FAQ they have a question "why is my kitchen radio a better signal" A: there is no telescopic antenna

    This tells me there is no option for connecting an antenna and likely not going to hold up in the car environment. If anyone has one and can confirm it would be greatly appreciated. I'd happily just buy one of these if the 2 points above can be ruled out.

    This particular board is the evaluation board and the antenna is hooked up to the headphone socket. You can decouple it easily and attach to an external antenna, or the standard breakout board has a separate antenna pin. As for performance, it's actually pretty impressive. That video I made I only had a 6" cable (it was all i had) going from the device to my speaker and reception was perfect. They recommend min 3ft, so 6" and still working isn't bad.

    Also the guy that wrote the Ardurino code said and I quote "Picking up FM stations from a plane flying over Portugal!" hahaha how true that is, who knows! I'm going to take the board out in the car at the weekend and give it a test drive. Will let you know how it goes :-)

    I'll keep that splitter in mind, I was actually looking at this http://www.scosche.com/motormouth-ii...-audio-car-kit as it would also solve the handsfree free issue. I've got tablet talk working and that's great for controlling another phone to make calls, but it doesn't pull the audio across. This could kill 2 birds with one stone, provide the handsfree and auto audio splitter for the FM. At least I think that's how it works, but need to find some more detailed info on it. I hate these sites that don't post datasheets!


    Cheers

    Man! These guys have already got it all there ready to go, but no public availability!! http://www.frontier-silicon.com/prod...e/DOK_App.html

    I was looking at possibility of poaching a venice from a store bought radio as I see some people on other threads have hooked them up to windows car systems. It has a I2C interface (same as si47xx) which could be controlled the same way via the IOIO. But then when you look at their site, they've already built it all. I don't understand why they don't just sell them direct to the public?? All our problems would be solved! LOL

    Oh well keep plugging away I guess

    Since I am in Sweden, DAB would work, but it all comes back to the antenna, is it good enough for a car environment, not same as moving while you jog. Usually it doesn't work.

    One more thing about the iVy, it basically is a radio unit that you control from you tablet/phone, so you would connect the iVy to your amp. I guess you can still play mp3/Spotify and so on over Bluetooth to the iVy and straight on to your amp.

    That is the problem with that unit, you will still have to hack it in order to connect a proper antenna. I was wanting to post that link a while ago but I thought people werent interested as they want a cheap android tablet, adding a radio can get costly. As far as I know one forum member is using the Keystone DAB module to connect to his android tablet via RasberryPi. If I remember well its a guy called dabbler in this forum, not sure if he has got it all working yet.

    Hej

    The quality of the module is the most important. Keystone DAB module are pretty good but I wouldnt say they are as good as the proven Venice module, Venice DAB module are used in real HU and high end Hi-Fi. I dont think I have seen silabs chip use in HU, although the SI4703 is better than the silab USB Radio stick but I dont think they are good enough. You can try it I supposed, but I do know both the Venice/Verona/Keytone module put the my Silabs USB radio to shame.

    If you were to put a radio together might as well use a good radio module such as the Keystone chip or the Venice/Verona. They both have good DAB receiver, the FM is not as good as a proper HU though but definately better than the silabs. Seeing both of you can receive DAB, might as well use DAB/FM module.

    I dont think its available yet.

    The Venice/Verona use UART, you can rip them out of a cheap radio

    Argos change their value product regularly so you might getting something different. Noticed mine is different to the pics on their catalogue (which is actually the same as the Tesco model but in white)


    Anyway here are the pics >

    1) Monkeyboard
    2) Verona carrier board I made, you cant see the Verona module as its soldered on the bottom side.
    3) Blank Verona carrier boards, top and bottom pics.

    Ill say, you might as well use a good radio module if you want an FM radio. These module does DAB/DAB+/FM/FM RDS so you cant go wrong with them.

    Does the android support USB Audio + HID? if so then I might be able to use my radio board on my phone. I have an HTC x one+ right here but I dont have the cable.

    Good luck

    here's an idea.

    Belkin wireless USB hub
    develop android app for Belkin from source on github
    develop android app for MitchJS devices
    use MitchJS cable to Directed FM radio
    use MitchJS audio selector

    Well well well....looky what I found. Anyone seen this? I check this stuff regularly and feel like it just came out of left field. It's a head unit made by scoche that is controlled through an android app on your phone (this includes FM tuning/presets).
