The Good
The Bad
The Bottom Line
Waiting for the Jensen VM9312's whirring, motorized faceplate to emerge, the first-time user is not immediately reassured that this is going to be a device compatible with the digital age. After all, there are car stereos out there nowadays without any moving parts at all. But with the 7-inch touch screen fully deployed, the Jensen VM9312 proves itself more than capable of the task of handling most in-car media sources.
Like the Jensen VMTS1195 that we reviewed last year, the VM9312 has an impressive range of audio-tweaking features. In addition to individual settings for standard EQ levels (including bass and treble), the system features dynamic range control (for enhanced playback at lower volumes); settings for subwoofer phasing; and a subfilter, enabling users to fine-tune the audio output by setting a crossover frequency for low-range sound.
Performance
We are generally impressed with the VM9312's iPod control interface: like other aftermarket screen-based in-car media players, it features a virtual wheel control based on the design of the iPod player itself. This is the only way to select or control songs once an iPod is connected as the player itself is disabled. The touchable circular dial enables users to pause and play tracks, skip tracks, and call up an iPod-inspired menu (playlists, artists, albums, songs, etc.).

For digital audio disc playback, the system shows folder and track information in an easily digestible format. ID3-tag information for individual tracks is displayed in a list on the left-hand side of the screen, while folder (or directory) information is shown on the title bar. When playing disc-based audio, the Jensen VM9312 displays an adapted version of the iPod wheel control, providing a straightforward means of playing and pausing tracks as well as skipping through tracks either one or six at a time. However, as with the iPod, there is no one-touch scroll feature available, meaning that discs containing lots of tracks have to be navigated with multiple button pushes.
We do like the VM9312's ability to bring up the source menu with a touch of the upper left-hand corner of the screen, but the system takes too long to switch between sources. Drivers who are looking to adjust the media source in those precious 10 seconds at the stoplight may find themselves frustrated with the Jensen VM9312, as it can take up to 15 seconds after selecting a source from the main menu for it to show up on the screen and start playing.

In sum
The Jensen VM9312 is an attractive package for those wanting basic media playback for digital audio and video. For a budget device, it offers a good range of features and customization options.
