Garmin GLO Bluetooth GLONASS receiver

I suspect that it wouldn't work with the hardware version of GMPC even if the registration could be changed. I think GMPC uses the Garmin data format when talking to its GPS directly by Bluetooth and don't believe the GLO has that capability.

However, I should have a GLO later this week and will certainly test that as I have both software and hardware versions of GMPC.

It is strange; every now and then GMPC will identify the GPS as a Garmin GLO and list the unit ID. But most of the time it calls it COM6: BthModem0. If I try scanning again it always comes up with COM6, regardless of which it initially finds.

You could just use GPSGate if the hardware version GMPC needs Garmin format, couldn't you? I don't know if you could still find a new box with the software version. If you could, I'd expect it to be pretty cheap. Looked recently and saw the hardware version going for about $45 on eBay.

Will be interested in your impressions Terry. I'm very pleased. The mat came yesterday, pretty much what I was expecting, very attractive looking. I'm thinking that the dashboard may not be such a great place with the hot sunny days coming. And the flat black mat won't help any either.

But the mat works well for placing the GLO on the center console armrest. They aren't kidding when they say "friction", it feels very sticky. I can even raise the armrest to open the compartment and the GLO stays in place.

Boyd, I do have both, the software version and also the hardware version of GMPC. However, the Lifetime Map Update has been purchased for the hardware version because Garmin didn't make the map update available for the software version.

Terry is most likely correct in saying that it wouldn't work because of the lack of Garmin format. GPS Gate would not pass the necessary hardware ID to the software, so it would have no chance of working even if Garmin would agree to change the registration...

It gets even better. Sitting here now repeatedly starting/stopping GMPC (asking for trouble, in other words ). It probably identifies the GLO by name 1 time out of 3. However, when that happens, if I press the GPS Info button to show the satellites, I get "stuck" on that page and cannot exit. The Home, Back and New Location buttons do not respond and neither do the minimize/close buttons in the top right corner. So all you can do is watch the satellite bars bouce around.

Fortunately the Slate has a hardware button to return to the desktop. I had to use task manager to kill GMPC. But as long as you don't go to the satellite screen, everything else seems to work. None of this happens when GMPC says it's using COM6.

Weird.

The fact that it identifies the ID suggests it is accessing the GLO directly via Bluetooth. You can tell GMPC to scan BT first but I have found version 5.00.60 does not respond reliably to that request. The .70 version does but has other issues.

Does it show the extra 'Accuracy' field?

No, it does not show an "accuracy" field regardless of whether the GPS is identified as GLO or COM6. Is that a feature of the hardware version?

That screenshot was taken using the software version and a 10x.

There's a lot I still don't understand about GMPC. When I started playing around with it again several weeks ago, I connected my 60csx. It recognized it, showed the satellites and started tracking fine. Then after a minute or two a message popped up that said it was an "invalid GPS". At that point it would no longer track my vehicle position while moving although it continued to display my speed and heading.

Later I realized I had the 60csx set for Garmin Serial instead of NMEA and figured that was the issue. Is that a bug or a "feature"?

Just like nRoute, GMPC recognizes the map as locked to a different device when you use the Garmin protocol. Or maybe that problem is the one ProITM fixed with a modified version.

One thing Marvin and I discovered when first trying the hardware version of GMPC was a way to make it scan BT first. It involved removing the ComPort D_WORD entry from the registry at HKCU\Software\Garmin\Que.

I wondered if maybe it was just a bug. The 5.00.70 changelog says this:

Quote:
Made Garmin Mobile PC compatible with use of eTrex X units, other newer eTrex units, Oregons, and Colorados as sensors.
The 60csx is an "X unit", but not an eTrex. I'm running 5.00.60. But it doesn't make sense to be able to use the same device in NMEA but not Garmin mode, does it? Doesn't really matter to me one way or the other, just one of those strange things about Mobile PC.

Just went for a short walk with the Slate and the GLO. I think these screenshots speak for themselves, so I will only add one word: Wow!

Have been meaning to post about the GLO battery life. Yesterday I left it running for about 13 hours and made it a point to have a GPS running and receiving data most of that time (maybe 11+ hours). It was still going strong at bedtime so I plugged it in to charge.

I just noticed the low battery warning today. It's been running about 14 hours today, although not always connected to an application like yesterday. However the Slate has been powered up the whole time and the GLO was paired with it.

Garmin's spec says 12 hours battery life, so I think that's probably about right,

My GLO arrived today and I have a couple of quick observations.

It creates 3 COM ports in XP and 4 in Win7

GMPC software version can't find it via Bluetooth until the COM drivers are loaded?? The hardware version won't see it at all.

It uses 72% CPU for GMPC on my Fujitsu q550 compared to 16% for the 10x.

S&T recognizes it OK. I haven't had a chance to try it while moving though.

Are you saying that Que.exe uses 72% CPU with the GLO? Wow, I am watching task manager right now on the Slate and it's mostly sitting in the 2%-5% range with occasional brief spikes between 18%-24%.

What do you mean about loading the COM drivers? When I first paired the GLO with the Slate, it went through that routine of loading drivers. Ever since then, it just works whenever I power up the GLO and start GMPC, including after a system reboot.

I still don't understand why it created the 4 COM ports. All my different software can only find it on COM6.

In all my usage, I've only had one glitch. Waking from sleep, none of my software could find the GLO and the blue light just kept flashing like it was trying to connect. Restarting the Slate didn't help. So I powered the GLO off and back on and all was well.

I'd say it's been extremely robust and a no-brainer to use, in sharp contrast to the Microsoft USB GPS that would stop working for no apparent reason several times each day.

Have fun, will be interested to hear about your experiences as you put it through its paces.

I am saying that using the GLO rather than the 10x with GMPC on the Slate increases GPU usage 50 to 60%. This is in map mode. If I try showing the satellites, it is up over 95% and the program hangs and ignores my input! I will try it on a Win7 desktop running the software version later to see how it responds as the Slate is pretty gutless comparatively speaking.

To use a Bluetooth GPS with GMPC, there is normally no need to load drivers as GMPC queries the BT stack directly to find and talk to a GPS. My example is on XP but it behaves the same on Win 7.
