What is it?
This item is a Holux Bluetooth
GPS device, model GPSlim236 or GR-236. It is one of the newer devices from Holux, and features the very latest consumer level GPS technology!
Read a review at PocketGPSWorld which gave it 99% out of 100%!
This is tiny! I couldn’t
believe its size when I first opened the box! I previously used an
older GPS model from Holux, I naturally assumed that since this had
the latest chipset and improved battery life, it would be larger.

Extra Lead - Turn your GPSlim236
into wired Mouse GPS
If you wish to
turn your GPSlim236 into a USB mouse GPS all you need is one
additional lead. This means you can then plug your GPSlim236 into a laptop or PC and
not have to worry about Bluetooth.
Not only that, but this
lead will also allow you to update the firmware on your device *at your own risk*,
making sure you will be running the very latest features on your
device. Please contact Navpal to
add this lead for only £12 to your order with no extra delivery
costs, or
visit Navpal's
eBay Store to purchase this lead separately.
Performance
This device runs the very
latest SiRF Star III chipset. What does that mean for you? This means you have
improved battery life, but most importantly it has much greater
sensitivity, allowing you to track up to 20 satellites at once; this
is far greater than many other products! Why do you need 20
satellite tracking? It means faster start-ups, so you need not be
sitting waiting in your car for up to 5 minutes before every
journey! However, perhaps the biggest difference of increased
sensitivity is when using in locations such as cities, sheltered
areas, woodlands or canyons (maybe not in the UK). In these
situations, older inferior GPS devices may loose signal, sending
you around in circles or crashing your navigation software.
From personal experience
at least 20
satellite tracking is a necessity, its no fun being boomeranged
around London because your GPS device is suffering from a lack of
signal due to interference caused by tall buildings. The only way to get out of
a situation like that would be to pick a direction, and just drive until a new
route is calculated, thanks to the SiRF III chipset, this is a thing
of the past!
Due to its sensitivity
this device can be used indoors, it can even work from inside your glove box! In comparison nearly all
other GPS devices I have tried need to see about 60% of the sky i.e.
it needs to be in front of the window, not with SiRF III though!

Why use
Bluetooth and not a wired gps?
Bluetooth brings an end to the
hassle of having to keep everything together in one place. It allows
you to choose the best spot for signal strength; whether in your car/van or even a lorry
(since Bluetooth has a
range of 10 meters), you sit in the driving seat with your software,
the GPS sits in the best signal area.
It is especially handy for for hiking, cycling
or when motorcycling since the GPS can be put in a pocket or a bag,
keeping your hands free, as well as your device safe.
As with other solutions
you wont have an impractical adapter hanging over the edge of your Pocket
PC,
adding to the weight, reducing functionality, as in most Compact
Flash GPS solutions!
