There are some caveats with your plan. The first is that you will need a separate GPS puck to use the radio with GPS control. You probably will not get a good GPS signal if you mount the puck behind the seat where your radio is located. The GPS puck likes to be on the dash, or by a window where it can get satellite signals. So plan for that. Also to use one of these radios successfully with GPS location control requires a fair bit of input from the user. By that I mean that the location data in the Radioreference database, which is where the radio will source that data, can be horribly inaccurate. That unofficial data is submitted primarily by members of these forums. It's rarely checked carefully for accuracy, and is highly subjective in any case. As an example, in a county near me the city of Astoria has the same GPS data as the county it is located in (Clatsop). Which means your radio would enable the Astoria channels long before you are close enough to receive them. In another case the city of Salem location data was entirely outside the city of Salem. That one has since been fixed, but you get the idea: you have to take the location data at RR with a grain of salt. When you "Zip Code Scan" you are using said sketchy data. You can of course edit the location data in your programming so it is more accurate and works better for you, but that can be a very time consuming endeavour if you're trying to program location data for an entire state for example. The last point I would make is that this scanner, like the 536 before it, relies on a micro SD card to store its programming. In the past many folks have had trouble with the 536 in mobile installations because if power is cut off to the radio abruptly it can corrupt the SD card. Maybe that issue has since been addressed, I don't know, but it is a potential problem to be aware of.
