The DAB+U device works as a virtual USB flash drive with mp3 files. All car head unit types have different USB protocol, because of this in some cases the DAB+U can't work with the current head unit properly, or won’t be recognized at all. You can try different configuration files on the DAB+U, to change the USB settings of the device. In some cases this is enough, in some cases not. We have a database of the officially supported car head units, we also tell there which config files are working with them. Therefore using this Compatibility selector is highly recommended, you can find it on the left side of the official Dension webpage:
If your car head unit is not mentioned in this database, then it is officially not supported. But if you already have the DAB+U device, you can try some configuration files with it, hopefully some of them will make it work properly or partly.
We are trying to improve our compatibility continuously and if there is an update we will upload it to the database. We suggest to check the Compatibility selector monthly.
Many thanks for your understanding.
Please read the next section “B. Configuration” for further information about the configuration process.
