O2 XDA Exec (aka HTC Universal). Shown while docked on a windshield mount with a built-in audio amplifier and Bluetooth GPS receiver (SiRF III chipset). Big screen, big sound. Served well as an in-car satnav and video player.



Nokia N95 with a built-in GPS receiver (TI chipset). My first mobile phone with a built-in GPS receiver. Quite disappointed with the receiver’s performance, which is worse than my oldest satnav.



O2 XDA Orbit (aka HTC P3300) with a built-in GPS receiver. My previous favorite. Its shortcomings (on RAM/ROM and CPU speed) when using iGo were the reasons why I chose the XDA Serra.



iPhone 3G with built-in GPS receiver and A-GPS support. Just a locator with no navigation application.
