Jensen and DUAL have both been recognized as some of the most affordable electronics brands available in the mobile electronics industry. It's especially difficult then when two brands like these release two identical products that are also priced similarly. Hopefully this review will help you decide on which in-dash touchscreen receivers you want by identifying some of the features most important to you.
Another great aspect of the VM9312 is the included auxiliary input adapter that could be mounted virtually anywhere in your vehicle. It allows for audio, video, 3.5mm, and optional iPod link auxiliary connections that is easy to get to and definitely convenient to use.
Some of the features on this Jensen car audio unit aren't so pretty however. For instance, consider that most in dash receivers put out 50 watts maximum per channel, but the VM9312 puts out around 40 watts maximum. Unfortunately, for those looking for pre-amplified connections, the Jensen VM9312 only has two pairs of RCA outputs, lacking the coveted subwoofer preamp output.
DUAL XDVD8181
As I had mentioned before, the two units are very identical. The XDVD8181 also features a 7" touchsreen. It even retracts the same way that the VM9312 does, but there are quite a few key differences. First off, the DUAL XDVD8181 will not be able to play as many file formats as the Jensen. This may not be a big deal if you don't use AVI, MPEG, or VCD, for those who do, it may leave them with disappointment.
An excellent feature of the XDVD8181 is its ability to expand as a navigation unit. DUAL offers the XNAV9525 as an optional solution for those looking to turn this head unit into a GPS navigation system. This will allow users to utilize the 7" screen as a navigation guide as well as multimedia playback display such as watching movies and of course, listening to music.
It also features standard 50 watts maximum power output per channel, something a little bit better than the Jensen VM9312; however, the DUAL XDVD8181 lacks the ability to function as an iPod Ready or Satellite Ready receiver. However the unit still features a 3.5mm auxiliary input adapter that is included in the box and just like the VM9312, it could be placed anywhere in your vehicle; and whereas the VM9312 lacked a subwoofer output, the XDVD8181 comes equipped with 2 pairs of preamp RCA outputs as well as an additional mono subwoofer output. This addition to DUAL car audio line of products is definitely worth looking into.
Overall
It's ultimately up to you as a consumer to decide on which is best for you. You may not need all the features available on one but may want some of the key features on the other. Nonetheless, both of these units are available at a low cost. You can't go wrong in purchasing in-dash receivers with 7" LCD monitors for less than $300.
