Nav Map Blinking?

I'm nost sure if this applies to your model, but you can try holding the power button for 6 seconds for a reboot to see if it helps. The info is from a Prius v manual in regards to sluggishness

Prius C's don't have a power button.

 

No PWR VOL button???

 

Sorry... Habit... I'm just so used to saying there is no power button...

 

I was sifting through the online version of your manual on Toyota's website, or the horrible replication of a manual, trying to find something similar to the reboot I saw in the online version of my Prius v, and couldn't, but definitely saw the PWR VOL button on pictures of what I did see.

When I had access to Toyota TIS I saw several TSBs for various Entune systems, which seems to be used across different models. Might be worth a shot to visit a dealer...

 

The update is mostly nav system fixes. There was a TSB with the details posted last month.

 

Navigation data update is different from system firmware/software update. Map update is going to cost you. Firmware/software should be free for warranty concerns.

I think this applies to the Nav in the Prius c too regarding map data updates:

2012 Prius v Navigation updates | Page 4 | PriusChat

Current available version is 12.1, which to my understanding is for 2012. New 2013 version should come out in or around October.

NOTE: Please verify the correct ACN part number with your dealer. They might not know the other one. I'll check if it applies to Prius c if I get a TIS account again....

 

I had just come from an engine thread and thought you were referring to the pwr button for extra power to the wheels.

 

Don't worry. My wife, son, and I test drove a Prius c once, and once only. It was a little small for us. I had to make sure I didn't put my foot in my mouth!

 

Here are the problems which the TSB for Entune 2.2.0 fixes:

After watching the video, it looks like you are having issues retaining a GPS lock. A reflash of the ROM could fix this problem... so best case, the Entune update fixes your problem... worst case, you have a faulty GPS locator.

 

Definitely sounds like the app didn't install correctly, or gps is dropping (since it was in the tunnel). A refresh of Entune *should* fix this as it will reflash the rom.

 

didn't look like a GPS fix to me, a lost in GPS wouldn't cost the map to blink what will happen is the vehicle icon will start drifting away from the road (esp when Map matching is not done right), otherwise the veh icon will be appear on a different road.

This is a graphics problems, issue with redrawing the map. What are you doing when it happen? sounds like U have something playing in the background. Care to share what do you have connected. Did the upgrade to SW 2.2.0 help?

if not U better try to get the dealer to get U a new box.

 

I've been to New York/New Jersey. Isn't the Holland Tunnel very long and it is a given that the GPS signal would be lost? In that case the Nav would try to follow dead reckoning, if manufacturers are still making that available. I would expect routing to continue after the tunnel though....
