Here's a satnav & PDA with built in GPS arial which is much better and faster than the HP that I bought a year and a half ago for £300.
This is my first deal but feel free to lay into me if this isn't a bargain. ;)
The Acer N35 is a complete navigation system that sits lightly in the palm of your hand. Stylish, compact and powerful, the N35 is the only mobile office you will ever need.
The Acer n35 has a powerful processor at its core and is based on Windows Mobile 2003 Pocket PC Premium Edition, making it not only a high spec PDA but an impressive GPS system.
Simply turn the Acer n35 on, flip up the antenna, select your mapping software and off you go. Use your n35 navigator to plan your route ahead for your next appointment and never be late. Voice prompts and different views will make your journey more comfortable and on its bright 3.5" LTPS TFT screen, you won't miss any detail. In addition to a fully professional navigation system you hold a full office and entertainment studio in your pocket.
