Questions and answers

Is the DEH-S31BT worth it at $30?
At $30.00 at eBay as of November 5, 2026, it is a low-cost way to add Bluetooth, USB and CD playback to a single-DIN car. Expect basic power and a small display at that price.
Will it fit my car?
It fits most vehicles with a single-DIN (7-inch wide, 2-inch tall) dash opening. Cars with a double-DIN opening need an adapter kit or a different receiver.
Does it work with iPhone?
Yes for Bluetooth streaming and calls, and USB supports iPhone 5s and newer. The Pioneer Smart Sync app itself runs on Android only.
Do I need an amplifier?
Not for normal listening. The built-in amp puts out 22 W RMS per channel, so adding a 4-channel preamp amp is worthwhile if you want more volume and headroom.
What is in the box?
The receiver, wiring harness, trim ring and mounting hardware are typical. Check the listing for included accessories, since a $30 unit may be sold without extras.
When is it cheapest?
Prices on this model swing widely. The $30.00 eBay price as of November 5, 2026 is far below its usual new price, so it is a strong buy point.
