Compatible GPS units

[NWI_Scanner_Guy]

Is there any kind of list any place that shows which GPS units are compatible with the 346XT?

I was reading someplace that if a GPS unit has a USB connection, then it wouldn't work with the 346XT.

I'm looking at a couple of GPS units at fingerhut.com, but don't know what kind of cable they use.

Thanks in advance for any light you may be able to shine on this.

You'll need a null modem/gender changer in line with the GPS's serial cable.

I doubt that any of the units at Fingerhut will work (they are all car navigation type from what I can see, and none of those output the GPS data). You need one that outputs the GPS data, which means a RS232 output unit (GPS data standard is NMEA 0183, which calls for a RS232 interface at 4800 bps).

As always UPMan, you're the best. Thanks for the quick reply.

After taking a quick look at page you linked to, I guess I'll have to search elsewhere.

Thanks again for the info. I really appreciate it.

If you want something that does more than just data output I have used this unit also and it works perfect. There are lots of docks and cables available too.

I was looking for a GPS receiver to work solely with the 396XT (I have a Mio Moov for navigation). In the end I settled on a Garmin Etrex H. It is a compact basic GPS that is really sensitive. If you get one of these you will not be disappointed.

I don't know where to ask this so I'll start here... I have MS Streets & Trips with GPS and was wondering if I could somehow use that with a 396XT linked to my laptop... Can anyone help?

I am just in the process of doing sort of what you are thinking of. Trouble is that the cable on the MS GPS recvr is actually a Serial to USB converter ( or possibly more correct a TTL to USB converter) the TTL voltage levels that come out of the puck where the cord plugs in are too low to provide data to the scanner. Easy to fix with a TTL to Serial converter chip. (MAX 232 is one brand.) You need to power everything with 5 volts (The power from the scanner batteries is fine). You will need to be willing to split the plastic case open on the GPS and do a little soldering or sacrifice the cable to hook things up.

I am going for the opening things up option and making a single unit that will just slide on and off the back of the scanner using the belt clip to attach it to. There will be a connector on the back of the scanner, under the GPS attachment, so no wires will be external.

Will post up details when finished, maybe later this week when my TTL to Serial converter arrives.

Stay Tuned!

As far as somehow using the GPS hooked to your computer, then passing the data on to your scanner, I don't know how that might be possible.
