Korean-based portable electronics maker Cowon has replaced its D2 media player with an upgraded D2+ version. The device has the same 2.5-inch 320x240 LCD touchscreen but with improved colors and can now be had with or without a DMB TV tuner. It can be ordered with 4GB, 8GB or 16GB of built-in memory, while external memory can be added via a microSDHC card slot that can support up to 32GB.

The new player also improves battery life compared to the D2, and adds a new calculator function, notepad, radio recording capability and an improved user interface. Either D2 can play back movies, music, DMB TV signals if so equipped and has a built-in electronic dictionary.

The new device will be available in pink, white, blue and black with a silver rear panel when it launches in Korea on February 24th. The current 4GB Cowon D2 is priced at $117 on Amazon. The 4GB D2+ is priced at the equivalent of $107, an 8GB version with DMB costs about $161 in its home market of Korea. Whether the D2+ will ship to the US is unknown. [via Akihabara]
