Tack för din fråga och feedback angående JBL Tuner 2. Vi kommer skicka din feedback angående displayen till den aktuella utvecklingsavdelningen så de kan förbättra våra nuvarande och framtida produkter. En Tuner 2 är avsedd till att användas med främst en telefon eller surfplatta som ljudkälla via Bluetooth. Vi kan dessvärre inte garantera att det kommer att fungera att använda en dongle eftersom det inte är något som vi har testat. Om du önskar att få ytterligare support från våra produktspecialister, är du varmt välkommen att kontakta Harman Kundtjänst via telefon eller e-post. Du kan hitta alla kontaktuppgifter här https://se.harmanaudio.com/support-contact.html. Tack.
