Sound of Tri State via eBay offers the Kenwood 2-DIN Bluetooth 6.2" Touchscreen Receiver for $189.99 with free shipping. (Electronics Express via Newegg charges the same.) That's the lowest price we could find by $9. Features include a DVD/CD receiver, AM/FM tuner, iOS and Android device control, and backup camera video input.
Dollar stores lure us in with their rock-bottom prices, but not everything is a bargain. We suggest you steer clear of these items.
