The story
Panasonic has announced it will end production of consumer car navigation systems, closing the book on a business that ran for more than 30 years. The move comes against the backdrop of free smartphone navigation apps becoming widespread, with dedicated car navi units long criticized for their high-cost structure — map updates every few years that can run tens of thousands of yen. On 5ch, threads buzzed with questions about phone navi’s data usage, heat issues, and GPS accuracy, while others pointed out that this only ends retail sales and isn’t a withdrawal from supplying automakers directly, leading to split opinions on how to interpret the news.

What people said
What a terrifying world we live in.
Just don't hook up the antenna cable, then.
Instantly memorizing the map and route — that used to be common sense for a Showa-era driver.
Give me a single atlas of Japan and I can get anywhere.
People who use it are pretty much all on unlimited data plans anyway.
The real problem with phone navi is heat — people leave it running and then walk away from the car with it still on.
Just like a car navi, it basically just receives GPS, so there's no packet data involved.
You use a little data pulling map tiles, but total usage is quite small.
Seriously though, since it's GPS-based, the data cost is negligible.
Whoever led that development must be out of their mind.
Honda's navi really is garbage.
I'm amazed they have the nerve to charge money for that thing.
Which brand should we be looking at for car navis going forward? 🤔
Just go with Carrozzeria (Pioneer's car audio/navi brand).
The ones still standing are Pioneer, Kenwood, and Alpine, but Pioneer hasn't changed much in about four years besides tweaking the free map-update window and the audio circuitry —
I bet they'll be the next to bow out.
And meanwhile poor Pioneer went and bet everything on car navi alone…
Pioneer's just left holding a car navi business with nowhere left to sell it (´・ω・`)
Using GPS on your phone drains the battery fast, and running it while charging builds up heat that shortens battery life.
In the end you wreck your phone's battery, end up replacing it sooner, and it's basically 'buy cheap, buy twice' for the tech-illiterate.
Toyota and Panasonic are tight as can be.
Wasn't Toyota's in-car camera and audio stuff basically sourced straight from Panasonic's automotive division?
I recall a Panasonic-branded Prius even racing in GT300 back in the day.
Even just in this thread, there seem to be quite a few people who don't get that this isn't a full withdrawal.
They're probably pulling out of navi software development entirely, or handing it off to Toyota.
Toyota's own navi is only marginally better than phone navi as it is, though.
Aren't most of the factory-installed units actually made by Denso Ten?
Toyota's new CAN bus is Denso-made, and Denso handles the vehicle control itself.
If it's hooked up to the factory display audio unit, it seems to pull data from the car itself —
there are also apps that just track movement normally on their own.
The major apps use the phone's own sensors to estimate position.
has that situation improved any these days?
Not even a little.
Still ridiculously expensive, and updates only come once a year, or twice a year at best.
There's no way it beats phone navi on update frequency.
Mine runs almost 30,000 yen once the three-year update period ends.
Though I can't say I've ever seen a genuinely original Panasonic product.
Well, it's the old 'copycat electric works,' after all.
That No. 2 mentality — never able to invent anything new on their own — is still in their DNA.
They used to be nicknamed 'Manishita Denki' (a pun on Matsushita meaning roughly 'the copycats') back in the day.
Even VHS, which took the world by storm, was actually developed by Victor (JVC), not them.
Won't they still put out map data?
This is just the end of retail car navi units, so factory-installed ones from automakers should still be supported, right? Can't speak for aftermarket units bought at an electronics store, though.
The maps come from Zenrin, so that part should be fine, right?
Re: #218
My dealer told me they've never actually seen anyone pay for a map update at that price.
Don't you lose track of which way you're facing coming out of a parking garage?
Doesn't seem much different, really — once you start moving, it figures out your direction.
That said, a dedicated car navi screen is easier to read than phone navi. It's mainly that searching for places is more convenient on a phone.
Background and Points of Discussion
Panasonic’s withdrawal from the consumer car navi market can be seen as one example of a broader shift rippling through the entire car navigation industry. The remaining domestic makers of dedicated, built-in car navi units have narrowed down to a handful of companies — Pioneer, Kenwood, Alpine — all of which face competition from free smartphone navigation apps. Dedicated car navi units often cost tens of thousands of yen for map updates every few years, and complaints about this cost burden came up repeatedly in the thread. At the same time, this announcement only concerns withdrawal from the “consumer retail” segment, not the end of Panasonic’s supply of factory-installed navi systems to automakers — a distinction that’s easy to misread. Some replies in the thread pointed out that “this isn’t a full withdrawal,” suggesting headlines alone don’t convey the full picture of the business. The structural weakness of costly map updates that dedicated units have long carried can also be seen as a factor pushing the shift toward smartphone navigation.
