Our take on the Sony XA-NV300T

Plug Sony's XA-NV300T navigation module into their XAV-602BT DVD receiver, and hit the road with powerful navigational tools just a touch away on your receiver's screen. Unlike many car GPS navigators, the XA-NV300T uses TomTom's IQ Routes feature, which compiles driving information gleaned from millions of TomTom users to create routes that base your travel time on actual drive times, not posted speed limits. So when you know you need to get there quickly, you'll follow the most efficient route for that time of day.

The XA-NV300T navigates with the aid of maps stored on an SD™ card, so you won't have to worry about losing your data signal, as with smartphone-based navigation.

Crutchfield Customer Review (What's this?)

so far, having troubles with this and my sony XAV-712HD. It would be nice if it was as easy as a smart phone to use navigation but from what I see so far to enter a destination you have to type in state first, followed by town or zip code, street, then street number. If you skip a step or try to move ahead it gets all messed up. The maps are outdated by a couple years, it shows a gas station in my home town that's been a pizza joint for 2 years. With my sony every time I start my vehicle tom-tom screen comes up first, annoying. Sometimes when I switch it back to the selected music I am listening to it switches back to navigation on its own. I am told its because my receiver does not have the latest firmware update but according to sony it does. This remains to be seen. I am going to keep messing with it but I am keeping an eye on my return date.

Crutchfield Customer Review (What's this?)

It's annoying to use because it automatically comes on when you start the car and it takes time to load. It would be way better if you can turn it on when you want it. I am probably going to disconnect it.

Pros: Graphics are ok

Cons: Not that easy to use compared to the portable tom tom I was using.

Least Expensive GPS Option

Crutchfield Customer Review (What's this?)

Least expensive way to Get a GPS Deck in your vehicle.

Pros: Cost, easy update,

Cons: Uses powered USB port

No updates since 2014!

Snowblind from Utah on 5/29/2016

ONE firmware update in 2014 and that's it! Speed limits are out of date on many of the western highways. Sony brings a good product to market and then orphans it. I bought this with a 712HD head unit because the shop I went with told me "Sony is back in the game!" That was in 2013 and there has been nothing new from Sony since. Stupid me for buying Sony again. They are a company that does not care about car audio.

Pros: Decent Nav

Cons: No updates. No support.

Great navigation unit

JohnH from Frisco, TX on 4/6/2014

Crutchfield Customer Review (What's this?)

I installed this in my 2008 Toyota Sequoia with the Sony XAV-602BT and have a helpful hint to suggest. I mounted the external antenna on top of the grate that is in the middle of the dash of this vehicle. I drilled a small hole near the back right corner so I could snap the wire through the side hole I made. The antenna receives signals well. The rest of the unit is mounted in the glove box just like they suggest. Good Luck.

Pros: Works great. Love TomTom.


Works great except for one thing...

Matt from Colorado on 1/2/2014

Crutchfield Customer Review (What's this?)

This unit, which is supported by Tomtom, works as well as my garmin pocket navigator. It looks good, sounds good, and is easy to use. It was super easy to install, plugs in via USB to the matched Sony head unit (XAV602). However, there is one major problem for the average user. The brochure included which directs the user to the website to download map updates is incorrect. It leads to a dead web link. Now, when I plugged in my unit, I found the maps to be fairly recent..... May 2013. But I did want the latest version. The Tomtom website is a bit confusing and misleading as it directs you to "connect your device" and install some utility to update it. Which also doesn't work, I got another dead link when I tried to download the utility. Not to mention the fact that there is no way to "connect" a car navigation unit to a computer to download updates. Turns out, there is a memory card which comes out of the Sony XANV which you can insert into your PC or Mac. After doing a global search on tomtom's website for the exact model number of this Sony unit, it turned up a support page which has a link to download a free zip file which had map updates to October 2013. (I bookmarked it for future use). Then you simply unzip the file to the Sony memory card, stick it back in the XANV and off you go. I didn't contact Sony or Tomtom, just through patience and persistence stumbled across the update link. Aside of this poorly designed update process, all is good.

Pros: Works well, fast, looks good, easy install.

Cons: A bit pricey. Update process is a bit of a nightmare. IT savvy users will eventually get it updated, but average users may get extremely frustrated.... Not sure how helpful Tomtom support will be, I didn't use them, figured it out on my own.

Crutchfield Customer Review (What's this?)

Put simply, the device works as it should but it's a very pricey add on... The maps are NOT current or even close to current. The product is dated back to 2010. Support for the device is seemingly non-existent since. I could not find where I could update the maps it kept sending me to a broken page... When you reach your destination, it does not stop the navigation. IT JUST KEEPS ON TALKING and cancelling or stopping the route is troublesome and annoying if you're still driving.

Pros: Works.

Cons: Dated (OLD). Pricey.


Hands-on research

Product Research


Head Unit Compatibility: The Sony XA-NV300T add-on GPS module is compatible with Sony's XAV-602BT DVD receiver (158XAV602B, sold separately). It simply plugs into the receiver's rear-panel USB (type-A) input. The add-on GPS module's map screen will display on the Sony receiver's touchscreen monitor and voice prompts will be heard through your vehicle's speaker system. You will use the head unit's touchscreen monitor to operate the XA-NV300T's navigation functions. 

TomTom Navigation (for US/Canada): The Sony XA-NV300T add-on GPS module features TomTom Navigation. TomTom navigation incorporates real world, real-time feedback, providing accurate mapping information. Maps of the United States, Puerto Rico, US Virgin Islands, and Canada are installed on the included SD memory card. You must install the SD memory in the XA-NV300T prior to using navigation functions.

Note: New map updates can be downloaded to an SD/SDHC memory card from TomTom's website.

GPS Antenna: The XA-NV300T includes a GPS antenna with a magnetic base. The antenna should be placed on the roof of the vehicle. The GPS antenna features a 16.25' cable terminated by a proprietary connector which plugs into the add-on GPS module. A self-adhesive base is also provide in case you cannot find a flat metal surface for the antenna. The GPS antenna measures 1.3125" (w) x 0.5" (h) x 1.4375" (d).

Map Screen (2D/3D):  Once the XA-NV300T add-on GPS module calculates your route, the map screen will appear. The map screen displays a real-time moving map illustrating your current position and intended route. Your route is marked with a red line, a blue arrow represents your current position, and a checkered flag marks your destination. As you travel, the XA-NV300T guides you to your destination with arrows on the map and directions at the bottom of the screen. The map screen also displays the current time, time left to your destination, current speed, and maximum speed. You can choose between a 2D or 3D map screen with a Day, Night, or Auto color mode.

Note: You can also choose to have the map screen run in the background, so you see and hear your source content while the navigation route is in progress. The unit will then mute the source, so you can hear navigation prompts when needed.

Text-to-Speech: In addition to the map screen, the navigation unit features loud and clear spoken instructions through your vehicle's speakers. When driving to your destination, the XA-NV300T will announce turn-by-turn directions, including street names and road numbers. You can choose between male and female voices in various languages. Your source audio will mute, while turn-by-turn instructions are heard through your vehicle's speakers.

IQ Routes: The XA-NV300T calculates your routes based on the real average speed measured on roads rather than the posted speed limits. IQ Routes takes into account the time of day you're traveling a road, and how rush hour traffic, pedestrian traffic, and traffic light changes can affect actual traffic speed. You will get a more accurate ETA and the fastest recommended route based on real world data.

Route Planning w/ Eco Route: Route Planning allows you to determine how the add-on GPS system calculates your planned route. You can choose from several different route types to suit your travel preference; Fastest route, Shortest route, or Eco route. The Eco route mode uses the driving data of millions of TomTom users, so the unit can indicate which routes are the most fuel-efficient to save you money and have a lower environmental impact. You can also choose to avoid or use the following road types; Highways, Toll-roads, Ferries, Car pool lanes, or Unpaved roads.

Advanced Lane Guidance: The XA-NV300T helps you prepare for highway exits and intersections by showing you which lane you should be in.

Drive To: The "Drive To:" menu is the simplest and most useful starting point in most situations. Given your current GPS position, you can use this to navigate to any given address, favorite location, recent destination, POI (Points Of Interest), and so on. You can choose from the following options.

  • Home: Once your home location is stored in memory, it can be quickly be chosen as a destination.
  • Favorite: The locations that you visit frequently can be stored as "Favorites". A Favorite can be chosen as a destination without having to enter its address each time.
  • Address: This option lets you enter a City, Street Name/House Number, Zip code or Intersection to navigate to.
  • Recent Destination: You can display a list of addresses, Points Of Interest, and other destinations that you've used recently.
  • Points Of Interest: You can access approximately 7 million pre-loaded Points of Interest (POIs) including fuel stations, parking, hotels, restaurants, ATMs, and lots more. You can search POIs near your current location, along your route, near your destination, near your home, or in a specific city.
  • Point On Map: You select a destination by simply tapping the map screen.
  • Contacts: You can navigate to a contact you have saved in your paired Bluetooth-enabled smartphone's phonebook.

Route Information: If you already have a route planned, you can explore it in various ways by choosing "Route Information". You can choose from the following options.

  • Route Instructions: This option provides a simple list of the turns involved and the distances or times between them.
  • Map of Route: Using this option presents your calculated route on the map screen in its entirety
  • Route Demo: This feature simulates visual and voice guidance of your route with a moving map.
  • Show Destination: This option displays the destination point on the map.

Change Route: Once a route has been planned, you can change it using the "Change Route" menu. You can choose from the following options.

  • Cancel Route: Simply cancels your calculated route.
  • Re-calculate Route: Recalculate your current calculated route with new route planning options.
  • Calculate Alternative: You can find an alternative route if you don't like the original route.
  • Avoid Roadblock: If you spot signs of trouble (such as backed-up traffic), you can choose this menu option to navigate around the traffic backup.
  • Travel via...: Choose "Travel Via" if you want to make sure the planned route goes past a particular location, perhaps to pick up or drop someone off.
  • Avoid Part of Route: This menu option allows you to avoid intersections that are known for heavy traffic.
