Questions about this item

Will the 3.5 mm jack on this player work with the aux cable I already use in my older car stereo?

Yes, the 3.5 mm jack lets you connect the player to any car audio system or speaker with a standard aux cable so you can play music through older equipment.

How can I confirm the Bluetooth 5.3 connection is active after pairing with my speaker?

The 1.5 inch LCD screen shows a Bluetooth icon once pairing succeeds and audio plays through the connected speaker or headphones.

Does the box include a micro SD card for the 128 GB expansion slot or do I need to buy one separately?

The player ships with 64 GB of internal storage only; a micro SD card up to 128 GB must be purchased separately if you want more space.
