The Power Acoustik PTID-8920 is a single-DIN head unit that features a fold-out touchscreen, region-free DVD playback, and DVD-RW compatibility. It can't play WMA files or hook up to your smartphone via Bluetooth, but it will put a DVD player in your dash without costing you an arm and a leg.

  • Responsive touchscreen controls.
  • Dimmer function for safe nighttime driving.

  • Can't play WMA files.
  • Power output is a little anemic.

The Good

The Power Acoustik PTID-8920 has one of the biggest screens you'll find in a single-DIN head unit, and the picture quality is satisfactory. The 7-inch flip-out display also functions as a touchscreen, which is a nice feature at this price point.

Earlier Power Acoustic DVD head units had no dimmer functionality, which made them somewhat unsafe for night driving, but that's not an issue for the PTID-8920. The DVD functionality is definitely this head unit's strong suit, and it doesn't back down from that challenge.

The unit is a region-free DVD player, which means it can handle your entire collection. It's also compatible with recordable and rewritable media, so you can burn DVDs on your computer and take them along on a road trip. To that end, the unit is also compatible with the DivX and XviD codecs and the VCD format. You'll also find a number of ways to expand the functionality of the PTID-8920.

The unit has preamp outputs on the front and the rear, so you can easily add an external amplifier if the need arises. There's also an auxiliary audio input on the front, and the rear video input can be plugged into a backup camera or any other video source. The unit also includes USB connectivity and an SD card reader. The USB port allows you to plug in a flash memory stick or an MP3 player, and the head unit can read music or video data straight off SD cards.

The Bad

While the Power Acoustik PTID-8920 shines as far as DVD functionality is concerned, the unit is pretty unremarkable on most other counts. It is capable of playing burned CDs, but it can't read the WMA format. It also lacks Bluetooth connectivity, so you can't pair your smartphone with it.

The 17 watts RMS per channel is also pretty anemic, so you definitely won't be blowing the roof off your car with this head unit. It does offer the option of preamp outputs that can be plugged into the amplifier of your choice, but that's an added expense that defeats some of the purposes of buying a budget-priced head unit.

The Power Acoustik PTID-8920 also lacks an HD radio tuner, which is something that should have really been included in a unit at this price point at the time when the PTID-8920 was first released. And if you're looking for an iPod connection or a head unit that can control an external satellite radio tuner, the PTID-8920 isn't the unit for you.

Power Acoustik PTID-8920: The Bottom Line

The Power Acoustik PTID-8920 is a mixed bag of welcome features, glaring omissions, and mediocre quality. However, you're not likely to find a better DVD head unit with a 7-inch screen in the same price range. So if you're in the market for an inexpensive, bare-bones head unit that can play DVDs on those long road trips, the PTID-8920 will suit your needs perfectly.
