- AQ DRAGONFLY is what I use (along with a requisite cable adapter) … its a small footprint for my iPhone with good results…. And comparatively cheap.
- APPLE LIGHTNING TO USB CAMERA cable out from the iPhone
- insert AQ DRAGONFLY USB
- 3,5mm cable out to audio input in the auto head unit .
- there are other bulkier options. Any and all will be an upgrade to the standard basic Apple iPhone output.
- Regardless, also invest in and download a 3rd party HDPLAYER app to play the hi-rez files and improve your streaming output as an upgraded playback app to APPLE’s own; and worthy of a step up to an external DAC.
