[MTCB Android Head Units General] typos1:
There are several DAB options for MTCB head units :

1)The RTL type DVB-T/FM dongle and the Wavesink app, see this thread in the hardware mod section: http://xdaforums.com/android-auto/mtcb-hardware-development/adding-dab-functionality-t3208344

2) Use DVB-T card or module specifically for MTCB head units and use the "radio" function. These can be bought with the head unit or purchased separately. Some manufacturers like KGL/HuiFei use and add on box, others like Klyde, use cards mounted inside the unit. In factory settings, at the last count, there were about 12 different types of TV tuner that can be selected.

3) Or use general Android USB DVB-T dongle and use the "radio" setting on its accompanying app. If this method is chosen, obviously you dont need to go into factory settings and pick a tuner, as these settings are only for DVB-T tuners bought with/for MTCB head units.

(Radio through a DVB-T card IS digital (using either MPG2 or MPG4 depending on the type of DVB-T tuner you have) but it is not DAB. Its also dependant on what radio channels your country chooses to transmit over DVB-T, for instance in the UK in my local area, none of the local stations are transmitted and not all of the national ones are either.)

4), 5) & 6) Dension sell 3 Android DAB products, one that uses BT to connect (which may prove a problem with the BT implementation on MTCB head units, edit: May 2016, the BT type seems to no longer be available), one that connects via USB and 1 that uses FM modulation (which means station names/info displayed via RDS in the FM/AM radio app, but a separate controller for the DAB for changing channels is needed) see here : http://www.dension.com/products#dab-radio-solutions

7) Navall sell a DAB module for their units, they sell both KGL (Hui Fei) units and also the Ownice head unit (the Ownice is NOT an MTCB type unit) see here : http://navallstore.com/Options/DAB -DAB-plus(Digital-Audio-Broadcasting)

8) Joying sell an add on DAB box (its not L band compatible though) : https://www.carjoying.com/joying-di...iversal-android-car-auto-radio-head-unit.html

9) FIAMM make a DAB antenna with built in tuner and BT, so youd simply install the antenna and use BT on your head unit to connect to BT (there is an app available), how it would work with the BT on MTCB head units, however, is unknown :

10) And finally Klyde sell a DAB module specifically for their units (I ve just bought a new Klyde head unit with it). They use a DAB module made by Shinwa who also supply DAB modules to Blaupunkt, Pure and Philips. I m told it is not retro fittable as modifications are needed to the board, I ve tried to make it work on my non DAB Klyde unit. but I ve had no luck, so far at least. Its a separate module, but its quite small (approx 10cmx4cmx5cm). Its small enough to be mounted inside the unit, something I intend to do with mine. It uses the DAB app that started appearing in ROMs from June (2015), although they have recently updated it. I ve added pictures of the module and the new app. It works quite well, although I m not over keen on the interface of the app personally, but it can be modded like any other MTC app. As the DAB app appears in ROMs since June, its been developed by MTCB (who develop ALL the software for ALL the MTCB type headunit, which is why they are so similar and have interchangeable software, WHICHEVER manufacturer version you have) this may mean that the other manufacturers will have OEM DAB options soon - I m sure MTCB have not developed the DAB app just for Klyde. So far at least, Klyde is the only company selling DAB units that use this app, AFAIK Navall use a different app and set up.
