This will take a few posts to show all the pics. I did an over the top install of an internal GPS module in the 996 with a cable to connect it to the 15 so both scanners are using the one unit. First pic is of the module on the bench being tested. Then the cable to supply data to the 15. I also made a cable to update and monitor the GPS. The antenna is nice and small. I used a 7805 power regulator. Note that with it hooked up to the three wire connector it does not get power if you are using the AC adapter.
