"NaviBlue NBC3500 is your basic starter navigation system from an unknown company. This could be scary at first - but at $155 you can almost risk it. The specs look OK too. It uses the sensitive SiRF Star III GPS receiver that almost everyone else uses it. Comes with a mid-range 1250mAh rechargeable battery and runs on an Atlas II 300Mhz processor.
NaviBlue NBC3500 has multimedia capabilities too - it supports MP3, WMA, OGG, Vobis, JPG, BMP, and GIF formats. Maps of the U.S. comes pre-installed on an SD card which has 1GB capacity.
We’ll be sure to add this to our sub $200 GPS systems list."
