Navman's iCN 550 is a hand-held or dash-mounted GPS device that sells in October 2010 for upwards of £220.9. There are bigger screens in the company's arsenal, and fuller touch screens that don't need a stylus to operate, but a 4-gigabyte hard drive can store all the data you'll need, and a remote control can let you drive from even the back seat. If your Navman iCN 550 is locked, you can probably unlock it by upgrading its software. If certain maps still appear locked, you'll have to pay for those.
Connect your Navman iCN 550 to your computer with your USB connector. Turn both devices on.
Enter your PIN on the keypad of your 550, if you've programmed one. For some, this may unlock the device. If not, proceed to Step 3.
Navigate to the second link in the Resources section and scroll down to the last software update, called "N-Series, iCN Series & PIN 570 Software Update." Click next to the listing, where it says "Download Software Update."
Click "Save File," when prompted, and the upgraded software file will be downloaded to your Downloads folder.
Double-click on the icon for the upgrade after it has fully loaded. Select "Run," then follow the prompts to download the new software to your Navman. This should unlock general functions and the device's base map, but additional maps--by region or overseas--must be purchased the Navman store. Contact Navman support if your device remains locked.
