There have been simpler DAB plug-in devices for some time, without a larger colour display, directly in the cigarette lighter with BT playback option from the mobile, depending on the product, this is done in higher or lower sound quality, depending on the BT standard, and DAB+ reception, and often FM as well. There are currently several suppliers in neighbouring countries. The sound goes to the car radio via FM or cinch connection, I have the aux cinch connection for this right next to the cigar lighter connection. They are usually easy to use, and usually come with a cheaper foil aerial to stick on the window, which is actually not ideal. Price range 40 to 70 Fr (at today's exchange rate, ex shipping). With better aerial option about 20 Fr expensive. FM sound transmission has disadvantages, because when driving in the other transmission range, or in fog with overreach, the own adapter signal is sometimes pushed away. Cinch is therefore better. With FM, however, the station information is also transmitted and appears on the car radio display. Now that the SRG is switching off, the problem of the signal being pushed away is largely solved. It's a pity that Digitec hasn't made private pension provisions. Will these cheaper products be available from Digitec soon?
