So I made my yearly summer pilgrimage with the family to Whitefish, MT from San Antonio, TX this week and arrived
This year I decided to forgo using a HomePatrol and instead use my very hobbled 536 with the GPS puck and Wifi Dongle coupled with an older iPhone 4S with the Siren App. The reason my 536 is "hobbled" is because it was part of the first production run, so it has the headphone jack problems along with the clock problem. I just never got around to sending it in for repair. For an antenna, I used a Baofeng VHF/UHF antenna that I ordered from Amazon the week before: Amazon.com: Authentic Genuine Nagoya UT-72 Super Loading Coil 19-Inch Magnetic Mount VHF/UHF (144/430Mhz) Antenna PL-259: Cell Phones & Accessories
Here are some notes and observations:

Here are some notes and observations:
- I installed the 536 in the back of a 2016 Cadillac Escalade along with the GPS hockey puck and the Wifi dongle. There is a conveniently located 12V cigarette lighter plug located on the drivers side all the way in the back with a pocket that all the equipment fits nicely into.
- Because my 536 hasn’t been repaired for the initial run problems, I connected a ground loop isolator between the external speaker audio out and ran an audio cord to the Aux-In connector located inside the center console. That provided decent audio through the Escalade’s sound system, but some improvement is needed there. Lots of ambient hissing noise between scanning systems, and still a hum is present. I suspect the 536 audio hardware fix is needed, and I’ll do that eventually.
- For the trip I downloaded and installed the latest full database. I configured the 536 Wi-fi dongle in Access Point mode, and set an easy to use SSID and Password.
- I used an old Apple iPhone 4S for the remote control of the 536 - so I wiped it clean and made sure that the Wi-fi dongle's access point was the only one memorized. The resulted in the iPhone automatically joining to the 536 after about 10-15 seconds after power up. It was a pretty small screen though, but it worked fine as a remote control.
- The 536 was configured to use the full database. It wasn’t clear to me how to make sure that the GPS was being used to automatically load local systems, but after trial and error I figured out that once the GPS puck is connected to the 536 and locked on, it just automatically starts using it. That was further complicated by the next item...
- When using the siren app as a remote control, I noticed on the settings page Settings->Set Location->Setup GPS a setting for “Enable GPS Updating” - Figuring *this* was the way to make sure that the scanner updates using GPS so I enabled this. Big mistake. My first day of traveling was fraught with the scanner running very slowly, holding on single systems for minutes at a time, and generally acting sluggish. Turning this parameter to OFF resulted in the scanner just working properly like a normal Home Patrol and using the GPS regardless of this setting. My only guess is that this is a feature of the Siren App that allows GPS updates from the phone to the 536 without a dongle. Or not, I don’t know. But with it turned off everything worked fine.
- The siren app. worked OK, just OK. It’s a pretty buggy app and it needs some work for true mobile use, but I was still able to drive 30 hours working through the quirks. I noticed if the 536 powered off and then back on, the app either never re-connected, or did so in a manner that resulted in a “flickering” screen update and unexpected app behavior problems, like crashes when touching the mute button. Swiping to kill the app and restarting resolved the problems each time. For real mobile use, I would suggest that Uniden re-use the last connection settings if the scanner or app restarts instead of prompting each time (so I don’t have to restart the app if the scanner restarts). Also, I would recommend relocating the home screen options for “Squelch” and “Range” to the Settings page. Those, for me, are almost never used parameters unless in very unique circumstances. I would instead place the “Avoid” and “Next” options in their place. In mobile GPS environments, you are always avoiding stuff, and there are many times when you want the scanner to move along “Next” on a conversation.
- Turning the car off, and then back on via the ignition switch resulted in a power cycle of the 536 via the cigarette lighter plug. I was pretty worried about this, especially the integrity of the SSD card, but we never had a problem. This commonly happened when we pulled into a gas station to fill up, turning off the car was no issue, but starting the car back up resulted in the scanner power cycling, resulting in a complete reload of the database, reacquisition of the GPS, and then a reload of the database. This power cycle also resulted in the siren app restart needed as described above.
- Receive performance of the scanner was outstanding, as well as digital audio quality. The Colorado State system and the Wyoming State system provides wonderful coverage across areas traveling north on I-25 from NM to MT, and coupled with excellent RRDB coverage of those areas, you get everything on that trip.
