Haicom 204S GPS Receiver Review Date TBA

Review by Dave Burrows



Haicom have released the new 204 series of Haicom GPS Mouse. The GPS we are reviewing here is the new Haicom 204S with cable support for a HP iPAQ 2210.


The Haicom 204S carries the SiRF IIe/LP chipset as denoted by 204S, supports 12 satellites all-in-view, supports NMEA 0183 v2.20 and is waterproof. Haicom say they have designed the 204S to withstand harsh operating environments, so having this on the outside of a vehicle whether travelling in the town or off road should perform well.

Anyone that reads PocketGPSWorld.com regularly will know I am still a fan of the Leadtek GPS Mouse, and I do still carry two on the dashboard of my car partially for everyday use and also for backup when I'm using Bluetooth, but the Haicom 204S does appeal to me. Partly because it's waterproof, but also because of it's solid design. It's a completely sealed, no screws and it feels like it's properly built (unlike the earlier 203's).


Like previous Haicom's it has a translucent case so you can see the internals of the GPS, the square you see is the internal patch antenna. The Haicom 204S also comes in a variety of different cable sets.

GPS Base

The base of the Haicom 204S is magnetised so you can place this on top of a car and not have to worry about it letting in water due to it's waterproof design. It also has a rubbery base so it shouldn't slip too much when placed on a dashboard.
