POSITIONING: Get unwired with Kemix Solar Bluetooth GPS

I have never heard about Taiwanese GPS manufacture "Smart Choice Int'l Co., Ltd." or its lately released brand "Kemix" but their latest GPS Bluetooth receiver looks like a "smart" idea - I haven't seen with other GPS receivers before: it includes a solar panel on top which operates the receiver and charge the receiver.

It includes a host side Bluetooth interface (Class 2)supporting SPP protocol up to 10m and features the NMEA 0183(V3.0) GGA, GSA, GSV, RMC GPS protocols with an update frequency of 1 sec.

I have neither found a link to the company nor any other information except a report from last CeBIT over at PCMAG.COM which states it should be available anytime for around US$ 100.

What do you think? I like the idea - all the time I need my GPS, the battery is empty. :-(

Cheers ~ Arne

Good idea indeed.  Now I haven't heard of the company either. 

But I still have a few questions:

1) How long does the battery last.  Of course you will find some situations when you need to navigate at night.  If you go cross-country will it even last a whole night of driving? I doubt.

2) Does it come with a holster or something to clip it on yourself when you hike  (instead of drive)?  Some BT receivers can be placed in the bag and still get GPS signals. Obviously you can't do this here because it needs sunlight.

3) What GPS chipset does it use for the reciever?  SiRF Star III is the most state of the art chipset and I won't buy anything other than that.  I'm currently using its predecessor, the SiRF Xtrac v2.  Which is not bad either.

Price is good at $100, most new BT GPS receivers are priced at $170.

i like it very much.I haven't heard about this company as well.

i doubt that it runs perfectly.Why?
Well i have a similar device for my pda. A solar sun-call device, which charge the pda.You need about at least one day to charge fully, so i think it's not very confortable to use it.The idea is pretty good, but in reality not.

The price is good at $ 100 as well.

Does anyone know where i can buy this receiver ?

We are specialised on GPS and have seen the prototype 3 months agon at a big Computer exhibition. We tested a functional smaple and are surprised about the accuracity and long stand by of this GPS BT Receiver with solar pannel. Only 42mah Powerconsumption and perfect Power management combined by a 8 Staelittes tracking seems to be a perfect solution for a long Navigation. 8 Satelittes? Some like Nermerix chip set can receive 16 Satelittes, but nowhere on earth you can get more than 6 or 8 staelittes! 4 are enough for a 3 Diemnsional Navigation. And this solar GPS is fast and accurate. 8 Satelittes = less power consumption.
We sell them now and everybody is happy with the functions and Naviagtion resultes.
