I found out that my Holux M1000 is quite unusable for voice navigation because the fixes from the device come 1-2 seconds too late (it is very weird but that is what I am seeing with the Holux). This also means that I easily miss turns when driving. The cold start speed, sensitivity and battery lifetime are very good with holux m1000.
I also have Nokia LD-3W, LD-4W and N810 internal GPS, and they work much better in this context and fixes come accurately in time when doing voice navigation.
The cold start time of internal N810 GPS could be better but after I have the fix, then it works ok.
BTW, although the Holux can be used in "slave" mode with out pairing, it is pro'ly best to pair it first anyway.

The unfortunate part is that the m1000 technically gets a better signal than any sirf III chipset device.

Hope this helps

The Holux ALWAYS gets a fix within 30-35 seconds (even in the basement of my two story house). The 30 second figure is for a cold fix. If the unit has been off for a only a few minutes, it gets a fix in 3-10 seconds.
My N810 just took 3 minutes and 10 seconds to obtain a fix in my living room close to a large window. Then I shut N810 off for 10 minutes and tried to obtain a fix again. It took over 3 minutes. It appears that N810 tries to do a cold fix most of the time. Why Nokia, why?
In addition, the Holux typically sees twice as many satellites, and the signal strength is significantly better.
The Holux cost $40. After subtracting the cost of the battery, marketing costs, distribution, etc, the cost of the MTK GPS chip cannot be more than $10. The Holux is also very power efficient as it lasts over 20 hours on a relatively small battery.
Why Nokia did not use this chip in N810 is beyond me. Instead they went for the crappy TI GPS 5300 chip, which is also in their N95 and E90 phones.
Regardless of the chip, it appears that there is a problem with the GPS software. There is really no reason not to do a warm fix after only 10 minutes. I will open a bug.
I'm glad this worked for you but for the life of me I can't get my N800 to work with the Holux M1000. I'm initially able to get the bluetooth connection going but withing seconds it disconnects. What steps did you take to get it going? I've loaded both the software on the mini Holux disk and the Linux driver download from the Holux website. Please respond soon - just started a new sales job and need this to work desperately. Many thanks in advance.

The software on the mini Holux disk isn't needed (or used - there's no linux driver there that would work on the N800).
I've only used my Holux (M1200, which is quite similar to M1000) with Maemo Mapper.
I simply do as follows:
- turn on GPS
- turn on BT on the N800 (with switchonbt - MM doesn't seem to automatically turn it on)
- start MM
- go into Settings
- GPS tab, choose Bluetooth, and Scan
- Select my Holux
- click OK
- select GPS
- select Enable
That's all. And after that it's just a matter of enabling/disabling GPS (unless I want to change to another GPS, e.g. my old one.)

I just got the Holux M1000 and am trying to use it with Maemo mapper on my N800. It works great so far except I can't get the display to rotate as my direction of travel changes. The "help file" seems to imply that it should auto-rotate. Anyone know how to do this? Thanks.
I also have Nokia LD-3W, LD-4W and N810 internal GPS, and they work much better in this context and fixes come accurately in time when doing voice navigation.
