The Mio P550 was one of two PDAs manufactured by Mio as a replacement for the aging Mio A201. The P550 was one of seven new devices showcased at CeBIT in March 2006.[1] The Mio P550 was a member of Mio's discontinued "Digiwalker" product line, and runs on Windows Mobile 5,[2] with Windows Media Player 10 for portables and portable Office.
The P550, in common with all other "Digiwalker" PDAs, supports GPS positioning, and features a built-in SiRFstarIII GPS chipset. The Mio P550 is essentially the same as the Mio P350, only differing in the inclusion of Bluetooth and Wi-Fi in the P550, and the difference of colour (the Mio P350 is silver-grey, while the Mio P550 is black). Inclusion of the extra Bluetooth and Wi-Fi antennas was blamed for initial poor GPS, (as compared to the P350), performance of the P550.
The P550 also features a 350 nit touch panel.
