Nuvi 360T sluggish at following road - Sorted!!

petepda · Occasional Visitor Joined: Mar 10, 2007 Posts: 36

I spent some time last night downloading the PGPS camera database and a few POI categories into my Nuvi 360T, which appeared to go without a glitch. However, viewing the map whilst driving to work this morning, i noticed the arrow indicator was a good 30 yards behind where i actually was on the road virtually all the time and the graphics seem to be much slower to update too. I've only got the map detail set to "normal" in 3D mode (i had run it with Most detail before and it seemed ok). I think the only setting i changed after downloading the POIs and Cameras was the Proximity Points Alerts, which i changed to tick Custom POIs and Garmin Safety Cameras.

Any ideas why it's become so sluggish?

It's running 3.60 software with V9 maps - everything up to date according to Garmin's updater.

NOTE: I have changed the title of this thread as it has subsequently been proven not to be caused by the PGPS POIs or Camera database. Apologies to the team for implying this was the case.

Hi there
Can I suggest the following that may help.

No 1 A stupid one is that do you have the Wass Egnos on or off.

No 2, If you have the PGPSW speed cameras in do not use the Garmin speed cameras as well. I think that you will have 2 lots of speed cams trying to be used at the same time.

Hope that this works

Cheers

Thanks for the response barecheek.

1. I have WASS/EGNOS off - no idea what this is and what difference it makes though - can you enlighten me please?

2. I do still have the Garmin speed cameras in there i think - at least i haven't deleted them, so i'll give that a go too.

I've been investigating this a bit further. Even with "normal" detail on the maps (the middle option), it's only updating the screen every 2 to 3 seconds. It doesn't even recognise i've gone round a round about until i'm well out the other side. The pointer also seems to go sideways down a road (aka drifting!) after taking a bend , so it's recognising that i've changed direction but the maps haven't caught up. It also doesn't recognise that i've taken a slip road off a motorway until i hit the roundabout at the junction. It's generally so sluggish.

I'm thinking what else i may have changed recently. I took the TMC12 out in case that was causing it. I also took out the SD card i installed recently, just with some MP3s and photos, but that made no difference either.

I'll try deleting the Garmin cameras and report back tomorrow. Failing that, i'm going to remove the POIs i loaded first, then the PGPSW cameras to see if i can get it back to how it was.

You don't need to go to the trouble of deleting the Garmin supplied camera information simply disable the warnings by un-ticking the Garmin Safety Cameras check box - Mike

Hi M8

Do you have a route planned - Nuvis have a habit (especially when loaded with POIs and mp3s) of lagging when a route is not set, but cope well when a route is set (no one quite knows why though).

Thanks for these tips - i'll try playing with the WASS/EGNOS and unticking the Garmin cameras.

The other comment about not having a route set is true though - i've just been using it to monitor my daily travel to/from work. I'll try setting it a route and see how it copes then, but i've a feeling this may be it as i never noticed this lag when i first got the unit when i was getting it to calculate routes everywhere.

I'll report back soon with results.

Done some more playing with this:

- switched off the Garmin cameras - no apparent difference
- switched on/off WASS/EGNOS - no apparent difference
- moved unit to a different location in vehicle - no apparent difference

However, when i set it to follow a route, it seems more or less spot on, i.e. follows every junction and round-about as i cross them. How strange!

Thinking about it, i guess if it has an idea of where the car is likely to be going from a pre-determined route, it helps it narrow down the GPS data more accurately perhaps. I'm sure my previous TomTom running on my Windows Mobile phone didn't lag like this when not following a route though, so i'm not that impressed with Garmin for this! It's obviously not a limitation of GPS itself - more an inefficiency in the Nuvi. Surely i'm not alone in wanting to have the Nuvi running even without following a planned route, just to get warnings of speed-cameras etc.?

I think i'll set up a trial with the TomTom and Nuvi running side by side.

Anyone else have views on this?

I'm not sure what i'm seeing is the same as this though. As an example, i'm approaching a roundabout at usual speed, but even when i'm half way round it, the Nuvi still shows me approaching it. Likewise with side roads - i'll go way past the side road before the Nuvi even shows it on the screen, then it realises i've gone past it and jumps forward. I used to like using the TomTom just to see what's ahead, e.g. what's round the next corner, or how tight the bend is, but i cant do this with my Nuvi as it seems to be tracking a car 30 yards behind me!

Just thought i'd update this in case anyone has the same issue.

I wrote to Garmin and got a response today, as follows:

Thank you for contacting Garmin Europe,

A master reset will resolve this. To master reset the unit please try the following;

with the device switched off, hold and press the top right hand corner of the touch screen, power the unit on in the usual way, as soon as the unit powers up, release the power button, but not the screen. The message 'Do you really want to erase all user data' will appear. Tap yes and then reset the device as prompted. wait for a gps fix before setting off on your journey.

This has happened due to no fault of yours. The unit has collected corrupt information from the satellites. This can happen occasionally if the signal is blocked by tall buildings etc. however this is not common.

I've followed the above procedure, which didn't erase all my favourites and POIs as i had expected it to. I'll try it out on the road tomorrow and let you know if it's sorted the problem.

Very pleased to report that this process has cleared the fault and the unit now follows the roads more or less spot on!

Thanks Garmin Customer Support!!
