Streetpilot 3 satnav vs windows 7 on my laptop

[Theoneattheback]

Hi,

Can anyone help please ?

I've got a new, unused, unregistered street pilot 3 sat nav. I've loaded the mapping software and it looks fine.

However when I try to down load to the memory card by plugging in the lead to a USB port in the lap top it can't find or recognise any of the COM ports. I've been told that it's because my windows 7 operating system won't recognise the somewhat old street pilot kit.

I've been into the garmin website, and I've down loaded everything that I can find. Is there another driver that I need to down load ? Or could someone transfer some mapping into my memory card if I sent it to them ?

Cheers,

Nick

IIRC the card downloader was a serial port device, that could be made to work with a usb if you had a converter.

But messing with a SP3

I'm pretty sure mine old SPIII card reader/writer is USB but it's a long time since I last saw it.

I'd start by downloading the latest drivers -

So what was the serial lead for on this piece of GPS history?

Seems the card reader is a usb: http://www8.garmin.com/manuals/45_USBDataCardProgrammer.pdf

The lead to link the SPIII to PC in order to update the firmware and to send routes and waypoints to it was a serial bus. I also have a serial lead that also has a 12V cigarette lighter plug on it. I used to use it to power the Streetpilot in the car while also sending an NMEA signal to the laptop so that I could navigate on that.
