I use a mag-mount puck on my trunk lid. Works greate, and I can easily remove it for car washes or long term parking...

to davidmc36: I found a USB to Serial adaptor for the GPS
USB to Serial RS232 DB9 9 Pin Adapter for GPS Garmin 9p - eBay (item 320314832981 end time Apr-27-09 19:42:07 PDT)
I think I will give it a try.

Lots of similar items on the web. However, there is nothing that will convert to allow a USB device (like a USB GPS) to operate on a computer that has only an RS232 port.

This will NOT work! Don't waste your money. Devices like this one are meant to TAKE IN SERIAL and OUTPUT TO A USB port of a computer. Not the other way around. When this adapter is properly installed with the appropriate driver, a virtual com port is emulated on the OS ie. COM 10. You then point your software running to this virtual com port. This is usless for a device looking for a straight serial stream, such as the 996.

There is no reason for you to drill any holes. Any decent puck GPS will work just fine on either the dash or rear deck of a car. I have a Garmin 18 LVC in my car and it just lays on the back deck. Zero problems. Even the lower end Deluo style GPS receivers work well this way.
As UpMan pointed out that will not allow you to connect a USB GPS device to the serial port on your scanner. It would be kinda like trying to push a rope up a hill
. You don't have a mummy and a daddy there, it's more like two daddies:twisted:. They should almost be more correctly called a Serial to USB adapter. In other words, you can't get there from here.I would still be interested in checking out whether the USB interface for the Pharos puck that came with Streets and trips is in the cable or in the puck. The puck has ten or fifteen pins where the cable plugs in and the other end is obvioulsly a USB plug. Could you hack up a serial cable straight from the puck?

My "puck" is just stuck to the inside of the windshield with two sided foam tape. Upper right corner, out of sight(sort of) out of mind. I have the Garmin GPS 18 and the biggest comlaint that I have with it is the size of hole that would be needed to route the wires better, wish I could unplug the puck.
Are you saying this cable will work with the 996 and a Garmin nuvi 300 series GPS? I ask because I use 2 GPS devices (eTrex Legend and nuvi 360) and this cable would eliminate the need to use the eTrex.

what puck model of GPS do you recommend for the 996T?
thanks

This one is a dandy:
GPS Receiver for Uniden Bearcat BCT15/BCD996T
There are others, so long as they have a serial connection and NMEA output you should be golden.

So you see why I am wondering if you could hack a serial cable for the S&T Puck. Here you can buy the reciever as a separate unit and the cable is what makes it USB or Serial.

In theory, most GPS receivers have NMEA serial output available somewhere in their guts (because AFAIK, all the major chipsets output NMEA). However, finding it, buffering to it, and getting it out to a usable connector...
GPS for the 996
I have been using the Garmin 18 serial version for two years now. I have it mounted on the corner of the dash and it works great. I have never had a problem with it and it is a great additon to 996, much better than locking out systems manually. I think its the only way to travel. In fact I just picked up a BC15 and I am gonna use the same GPS for that one as well.

Maybe I should just install one of these inside the 996

Expensive solution ($99 for the board, $49 for the antenna...)

What kind of space is inside of the 996? Looks like I need to get working on an internal GPS module. I already have several GPS modules designed into several of my products:
http://www.rpc-electronics.com/rtrakpromo.php
With a little bit of time, I can produce a simple GPS module that outputs 4800 baud RS232 serial data. Knowing the size of the module and the minimal extras to make it work, I know I can make it slim enough to put inside the scanner.

This is true. Usually, its at a TTL level, either 5V or 3.3V. Luckily, it's not hard to "convert" this to RS232 voltages +/-12VDC. That is why I am thinking it makes sense to just design one from the ground up since I already have 90% of the circuit designed for another product of mine.
For sure not the most economical way to go, and not for the faint of heart either. Not as bad as it looks though, those are CAD and I got an antenna off Ebay for 15CAD.
More like........why climb Mt. Everest..........Because I can:twisted::twisted:
Iv'e had mine open. There's enough to put ten or fifteen of those little matchbook size modules that I linked to.

The module you linked to is a great one, but huge compared to the chipset I am referring to. The chipset I work with is about 10mm x 10mm.
