Sorry… I should have been more clear.But that's 5 at one dealer so may not be as bleak as you think. Posting on forums may attract more with simlar issues.
My map shows instantly too with a location (sometimes a block off).Every time I drive out of my garage the map is already up with my location displayed
Have you heard anything else?So I took my LC200 in to the Toyota Service center two days ago for them to fix the GPS. Spent 4 hours there.
Eventually they told me it was the firmware. It needed updating/calibration - they said.
I was dubious but accepted.
The GPS signal acquisition actually seemed to be better for the rest of the day (though I didn’t drive it much).
Today the GPS is back to taking 4 min to find a signal and blinking off when I drive under trees.
So I’m back at Toyota now.
I got to talk to the technician this time. I’m not sure he did any more than do the location GPS reset and the GPS tire calibration on Tuesday.
But he and I just drove around and I was able to show him how slow/wrong the GPS is.
He said he now needed to escalate within Toyota.
Wonderful!
@gaijin,So... Think any of this might apply to your use case? Has your NAV been actively receiving for periods longer than 25 minutes at a time recently?
@gaijin,
Could it be that it’s much longer than 25 min? More like 45 to download all the necessary data?
Sub- frame | Word | Description |
---|---|---|
1 | 1–2 | Telemetry and handover words (TLM and HOW) |
3–10 | Satellite clock, GPS time relationship | |
2–3 | 1–2 | Telemetry and handover words (TLM and HOW) |
3–10 | Ephemeris (precise satellite orbit) | |
4–5 | 1–2 | Telemetry and handover words (TLM and HOW) |
3–10 | Almanac component (satellite network synopsis, error correction) |
Did you ever resolve this? Mine is doing something similar….@gaijin,

I ask because after all my road trips this summer, my GPS was pretty solid for a while, even back here in Houston. But I haven’t gone anywhere in a bit and it’s starting to act wonky again.
I haven’t taken it back to Toyota yet because, like I said, it was good here in Houston for a few weeks upon my return.
So either there is an intermittent disconnect somewhere in the system that causes it to go awry or its that my GPS isn’t downloading the data correctly when I’m in Houston.
Where/how would you attach it?Would hooking up one of these help the NAV systems's GPS?
It is a blue tooth connection.Where/how would you attach it?
Despite my LC gps often being wildly inaccurate due to some issue it has, I still use it when it’s working.Curious to hear who in here still uses the OEM head unit for regular daily GPS nav. I have installed beatsonic and use carplay now. Forgot the GPS in the head unit exists, but it is sometimes useful when out of cell bars and you forgot to download the maps to your phone. Anyway, do you guys still use it like for day-to-day drive, etc? I imagine the accuracy in terms of ETA and traffic must be abysmal in comparison to the modern live updates we get in our phones.
