Anyway, I got an email from them saying that they’ve registered the device for me and they also threw in a free upgrade to City Navigator North America NT 2010, which is great, and that’s what started this thing in the first place.

So, while a little slower than usual, Garmin support came through again. Thank-you Garmin, I shall continue to recommend your products!

I’m a fan of Garmin GPS receivers, particularly devices like the GPSMap 478, a wonderful chart-plotting GPS. I also have a StreetPilot 7500, a nice large-screen GPS that I use in the truck. I’ve spend thousands on Garmin hardware and maps since my first Garmin device, a GPS 12, back in 1995. If you count the devices I’ve bought for others and my referrals that total is well north of $10,000.

A while ago, maybe in mid-late 2007, Garmin updated their internal systems at my.garmin.com. I had multiple GPSes registered with them, including the StreetPilot 7500. The old system was never brilliant, I blame the DRM they have around the mapping data, but that’s another subject…

Anyway, I want to upgrade the 7500 to the latest version of City Navigator North America NT, the 2009 update. To unlock the maps, you have to have a registered device. During Garmins update to my.garmin.com my previously registered 7500 disappeared. Now, when I try to register it again my.garmin.com rejects my serial number.

I’ve been extremely happy with Garmin support through the years, in fact they managed to next day me a replacement mapping CDROM when I was out of the country, starting trans-Sahara trip, to replace a damaged disk. They have been pretty responsive so far with my registration problem, until I received this today (the issue had been passed to their IT department)

We have contacted our IT department and requested another update. To answer your questions:

We have stressed the importance of getting this matter resolved and I am hopeful that we can get this matter resolved quickly. Thank you for your patience in this matter.

As this issue has been outstanding for 3 weeks, I’d love to know what the “IT Department” are doing. The very phrase makes my blood run cold, and I’m in IT guy! Some transparency would be greatly appreciated.

Ideally, I’d like to know what IT have done in the 2 weeks since they received this ticket from their support guys, what they are planning to do and why they can’t escalate it.

Remember, all I want to do is give them about $100 for new maps. All I need is a valid serial number.

I hope I don’t have to start buying and recommending other brands if they can’t resolve this. If anyone from Garmin feels like helping, the case number is KMM12787676I15977L0KM. Thanks!

I have to say, Valorie in Drobo tech support did a great job handling my case. It seems that it may be a PSU problem (yes, just like my Lacie drives!). Both the Drobo and the Lacies come with cheap Chinese-made PSUs.

As you can see from the photo, it should be capable of outputting 6.7A at 12V. My multimeter said 12.36V, though I’ve no way of measuring the current draw when active. Drobo support said that the 1TB Hitachi Ultrastar HUA721010KLA330 drives are a known “power hog”. The drive itself states a current draw of 850mA (I have 2 installed, the other 2 are 750GB Seagate Barracuda ES ST3750640NS, with a stated draw of 520mA, so there could be some truth in that. If this is the case, I know from personal experience that it’s possible for multiple restarts to corrupt volume information resulting in data being lost.

They are sending me a new PSU, so we’ll know soon enough.

Well, there’s a new kid in town. The Garmin GPSMAP 640 looks like it’s going to be the new favorite of overlanders. It addresses both of my issues with the 478. It takes SD cards, and the display is a 13.2 cm (diagonal) with a resolution of 800×480 WVGA (the 478 is 9.4cm on the diagonal and has a resolution of 480×320). It’ll calculate faster than the GPSMAP 478, with SD cards it can support more memory, but it is a bit bulkier (15.0 x 10.2 x 4.8 cm vs the 478 at 14.5 x 8.1 x 4.8 cm). 

There is also a GPSMAP 620, which is physically the same at the 640, but doesn’t support the XM Radio and XM Weather (which I use frequently, very handy having radar overlays when you’re in the mountains in the summer), and doesn’t come with any maps preloaded. It also costs $200 less at MSRP. 

For XM Radio and XM Weather, you’ll need the new GXM40 antenna (with the very odd MSRP of 267.84). It seems the old GXM30 won’t work with the 640, and you’ll have to transfer your existing XM subscription to the new antenna. 

The GPSMAP 640 isn’t available until Q1 2009, with an MRSP of $1199 (but already available for pre-order from around $950).

As soon as Ram Mounts have their brackets ready, I’ll get one ordered.

I decided to keep the factory amp and speakers, the amps is fine and I’ll replace the speakers this summer. That meant connecting the new head-unit to the existing wiring. Now, I’m not going to hack a factory wiring-harness unless I have to so I managed to get a harness that was close enough to work.

As the 1997 D90 was the only year with this configuration, I had to figure out what each on the pins on the factory harness was for. There was some documentation on the web (1, 2, and a useful 3), but I also had to add connectors to the custom harness so it would work with the factory harness. The Alpine unit came with its own unterminated harness, and good documentation (PDF link), it was easy to connect to my wiring.

The pinouts look like this: (click though for large version)

The pinouts for the 10-way connector are for the speakers and self-explainatory. The pinouts for the 8-way connector are as follows:

(Pin 1 is the top left, above the keyed part of the connector, pin 2 is below pin 1, pin 3 is to the right of pin 1, etc.)

1. Phone Mute – not used
2. Amp Trigger
3. Remote – not used
4. 12V+
5. Remote antenna – not used (power for an electric antenna)
6. Illumination
7. ACC – 12V+ switched
8. Ground

Once I had my wiring adaptor cabled, it connected to the factory harness and the x100 works like a dream! Highly recommended.

From Crutchfield, I ordered the following components:
Alpine iDA-X100 Head-unit
Alpine KCE-422i high-speed cable for iPod/iPhone
Receiver Wiring Adaptor for Land Rover
Antenna Adapter

I use RAM mounts on the Land Rovers and the motorcycles – I’ve used them for 7 years and never had a problem despite being shaken around off-road and overland. So after buying a Delphi Skyfi3, I naturally wanted a ram mount for it. They didn’t list one in their catalog, so I emailed them and got this response the same day:

We currently do not have a solution for that unit as it does not have a solid way for us to mount our mounts to their factory cradle. We currently do not have any plans to provide a solution for this particular device. If we see a tremendous demand for the Delphi device we may create a solution but we do not have any plans at this point.

Bugger. Still, the factory car mount may be ok but I doubt I’d use it on the bike. I’ll have to see what alternatives are out there.
