Is the DAB app just the same with bug fixes or a different look?

Hi!
Tried the latest version yesterday. At first it looked promising. Had a 10 minutes drive without any problem. Today the problem was back, many restarts necessary when driving about 10 minutes to my work Also, the cold boot problem is still there, and I forgot to mention that 3G isn`t working aither. It worked only the first day, never after. The symbol on the screen show when I remove or install the SIM-card,but the signal indicator doesn`t show any signal. It could maybe be the 3G antenna, but It is not tempting to take the HU out another time..

The DAB+ problem is the most important for me, as there is no FM here anymore. Could it be a hardware problem with the DAB+ receiver?

I don`t use the original antenna, I have this roof mounted antenna: I have a DC-block on the DAB+ receiver, and use the blue 12V wire from the HU for powering the antenna. The signal is very strong, but it could of course be something wrong with the antenna. I could try the original antenna just to troubleshoot.

What does it mean when the signal indicator alternates between 5 green bars to 5 white bars? When I lose reception this is what I see. The developer of the DAB+ app should be able to answer this question. I can ask myself if I have a support page, or an email address?

Some good news! Seems that the DAB+ problem was just the USB-cable. I first disconnected the antenna. The signal was lost when the antenna was disconnected, but came back with the antenna plugged in. The same result with the original window antenna. Then after a while the signal was lost, as usual, but didn`t come back with neither the original antenna, nor my roof antenna. After a DAB+ app reset the signal was back. I disconnected the USB, and the signal was lost. It didn`t come back when reconnecting USB. Then I replaced the USB-cable, and DAB+ has worked several days after! Tried both antennas, but this is clearly not antenna related. Can not be absolutely sure that the cable is defective, as it seems ok when used with my phone connected to the PC. But at least DAB+ is working with a different cable.
