The only viable DAB + equipment for car

I have tried seven different DAB + radios. Including five pocket radios, where the headphone and Aux cable serves as an antenna. This principle is fundamentally bad, because the reception collapses in the moment in which one enters into the Aux cable somewhere to an amplifier or the car radio because the grounded shield of the cable then prevented jegelichen reception. Even the tested car radio Imperial DABMAN 60 was hard to use when it comes to reception and sound.

This device, the DR 56, comes with a glass antenna. With this I have perfect reception, even if they still packed is in the car. Sticking I will only at the next opportunity. An outdoor antenna with magnetic base is in my opinion, not necessary.

Sound and output level of the device are hervoragend, much better and louder than the headphones out of pocket radios.
Power is supplied via the USB connector of the car. Thus, the radio will automatically turn on when I start the car. The device still also has an FM transmitter and a Bluetooth handsfree. Both I do not use, because my car has an auxiliary input and a speakerphone.

Hence my recommendation: this is the only viable DAB + car radio and its price absolutely worth it.
