Now here's an excellent example of an affordable, yet high performing in-dash navigation. The Power Acoustik PAVN-4210 is a single DIN head unit that has built-in navigation. The PAVN-4210 is Power Acoustik's answer to the increasing demand for vehicle navigation devices.

Display
First off, the front panel is slightly larger than a standard single DIN size mounting. This may be a problem for those with limited mounting space on their dashboard console. However, it does feature a large 4.3" LCD touchscreen monitor that is both bright and attractive to the eyes. A typical single DIN receiver features a maximum 3" LCD display, unless it is a retractable, flip-out type which could typically house a 7" LCD screen. The 4.3" LCD display is a nice feature to have, since it makes the unit unique as well as versatile. It could even drop to three different positions to accommodate for better viewing angle.

Compatibility Features
The PAVN-4210 is capable of playing common media formats such as MP3, MP4, and standard DVD/DVD-R/RW. But it could also play DivX file formats; all of which could be displayed as NTSC or PAL color system for greater compatibility. This means that the unit could play display video from virtually any country of origin where NTSC or PAL is the standard color system.

Expandability Options
This versatile unit is also capable of receiving (with additional accessories) Satellite Radio (both XM and Sirius). Satellite Radio information will be displayed on the screen which would display station information and current program. In addition, this in-dash navigation multimedia receiver features a mini USB port as well as an SD Card input, allowing users to play their favorite MP3 or MP4 files or even update their navigation maps.

Navigation Features
The unit comes with a 2GB SD Card with map information as well as 7 million points of interest. The internal processor is a 400 MHz Sirf Star III chip running a Linux-based software. This means that users will not experience much lag or sluggish performance while navigating and calculating routes while driving. The GPS receiver is even capable of receiving 20 parallel channels, allowing connection of up to 20 orbital GPS satellites which greatly reduces the likelihood of signal loss while traveling long distances. The GPS receiver will also receive signals from traffic alerts, notifying you of accidents as well as traffic status in major US metropolitan cities.

As you can probably gather from what is covered in this review, this affordable single DIN in-dash navigation is packed with features that are usually reserved for more expensive units. However, for the price that is offered ($429.99), you can't get a better deal than the Power Acoustik PAVN-4210.
