Integrates nicely but out of date with bad manufacturer support

Andy from Scotland on 2/10/2018

Verified employee purchase (What's this?)

I purchased this last year to add onto an XAV-XA100 receiver car play unit, it integrates very well, the guidance is as good as any other tomtom device I've had but lacks the interactive speed cameras and traffic info my main issue is that the latest map I have is the one that came with the unit (dated August 2016!) when I contact Sony they say there are no updates, when I contact TomTom they point to an XAV nav update that simply does not work. If you are happy with the old map then this unit is pretty good however a cheaper unit from tomtom will provide traffic and speed cameras. As for tomtom support they are unwilling to listen to the suggestion that the link they point to may be wrong. I'm pretty disappointed from both TomTom and Sony with regards timely updates and general support. I would not recommend this option to anyone without a disclaimer.

Pros: Fast - with a fast SD card I find it very responsive, Similar results to Tom Tom Go app on iPhone

Cons: No Safety Camera Support No Traffic Update Support Can't share or backup 'my places' SD Card Slot Location on same side as the connectors so mounting of device for SD access is impossible whilst keeping it tidy. TomTom Support was just wrong - disappointed at their ignorance. Sony Updates non existent , map is currently 1.5 years out of date.

Great addition to Sony XAV-AX200SXM

The SOny/Tom Tom Nav unit is very nice and I am pleased with the purchase. I added it to the SOny XAV-AX200SXM radio and they integrate flawlessly. It installs quickly and putting the antenna on the passenger side dash has worked well. The unit finds my location quickly and the UI and display are very nice. maps were already pretty well up to date. The search feature is very versatile compared to other units I have used. Allows passenger input while vehicle is moving so which is nice in our overly litigious/protected world. Lane guidance is very clear and sets the unit apart from using Apple maps or other Nav software. Nice to have dedicated NAV when I don't feel like using my iPhone. Wish it had traffic capability though-but when traffic is an issue, that's when I switch to Apple Maps or Waze. I have only found a couple routing mistakes so far (more than google maps, less than Apple maps). It is a little slower than Waze to recalculate my route when I chose to take a different route than the one laid out. Another feature I like is the way it notes gas stations/parking along your route that you can click on to find out which ones it is referring to (not perfect, but better than other apps I have used). Only negative I have is that installing in my glovebox (as they call for so that you have access to the memory card for future updates) is tight. With the wires coming out the top, when I shut the box, it is a little tight no matter how I route the wires.

Pros: Nice lane guidance, easy install, quick to find my location, versatile search feature, mostly accurate routing. Good alternative if I don't have my iPhone with me for Nav (or am using it for something else at the time). Better than Apple Maps, not as good as Waze.

Cons: Wish I could incorporate traffic info. Installation in glove box (as suggested) can be a little tight/tricky to ensure wires have room.
