DNS series head unit (new generation dual core RNS-510 alternative)

[wanxu]

Yep. There are some skins that make it not as terrible, though.

Did some more playing around. Found that iGo8.3.5 isn't a solution. It's ever so slightly more responsive when open, compared to Primo, but as soon as you start navigation/simulation, the same thing happens where everything just bogs down/slows down. Go back to the menu of iGo8.3.5, or stop the simulation, and it goes back to being responsive again.

So it's either that iGo8/Primo is being a resource hog during navigation/simulation, or the DNS just isn't optimised properly/fully, yet.

I don't understand why its so hard, when Primo/iGo8 works fine in many other units, many of which have 1/4 of the processing power that the DNS is supposed to have. Hell, the exact same copy of Primo works ****ing perfectly in my Eonon unit, even when simulating a 4000km trip, and that has a 500mhz processor, 128mb of ram, and essentially the same version of WinCE6.0.

Ugh.

It's easy: in this unit EVERYTHING is processed by the same processor, while in the other units there's a side to process the GPS and the other side process everything else.

Anyway, you can edit sys.txt in Igo to set it to use less memory. Check out these options, and don't use TTS voices:

[debug]
cache=2048
max_memory=143724405 ; 91MB
reserve_memory=396683
no_file_cache="1"
no_tmc=1 ;

But it should be exactly the same as every other unit? and it looks to be the same hardware as the S600, which according to Bazzle, works fine. Very strange!

So I've given both 9.6.13.267029 and 9.8.0.377454 a go, and both work better than 9.6.5. They still lag and stall on track skip, when simulating a route. I'm beginning to think that its the Simulation thats the problem, may not be realistic. Might have to give it a go on a trip and see how it goes. Because they all work fine and are responsive when its just sitting there displaying a map, or even once you've calculated and started a route, but as soon as the simulation starts it bogs down. Not sure how it works once you actually start driving. Will see.

Drove around a bit today with both 9.6.13.267029 and 9.8.0.377454, both perform about the same, but 9.8 is slightly faster in the menus etc, and is not compatible with any of the tweaks etc.

Still exhibit the same issues with SD playback. Maybe slightly better, i'm not sure, its really hard to tell. As soon as you stop/pull over, though, the lag goes away. Very strange!

To be honest, I really can't be bothered any more. There is little to no lag in FM radio or iPod playback, even during navigation, which is good enough for me.

I'm starting to think it may be an issue related to the CANBUS decoder (because the CANBUS stream seems to slow down to update every 2 seconds, then goes back to being normal speed when there is no lag etc) so i'm going to wait until we get the new chip before playing with it any more. Remember back when they first shipped, there were all sorts of horrible issues that were caused by the CANBUS decoder.

Otherwise, its still an optimisation issue, I guess.

No, because I assume that S600 works like older units, with the CPU just working with the GPS, so GPS is independent of the other side. If Igo is getting 100% CPU power, the music playback will continue as if its getting 0%. DNS810 works with the same processor, so if Igo is using CPU, music will be affected.

Where is Bazzle talking about this new S600 unit?

How do we know that thats how it works, though?

Bazzle mentioned it in my thread on fixmygps, here: iGo Primo causing unit lag

Bit of back and forth with Audiosources, they reckon that i'm the only customer that has complained about this problem, and that they've passed it on to the engineers to rediagnose.

Surely not though. Or am I going crazy? Everyone else in this thread is seeing the same issues too, right?

Yep. Mines worse than yours. It locks up all on its own without music playing.

Locks up when you're using the GPS, or just in general use?

Do you by chance have RDS turned on? FWIW, a few weeks ago I was playing around and turned RDS on, locked up straight away and had to do a fuse pull.

[asa572]

My nav is laggy no matter what!
I have had my unit freeze and have needed to pull the fuse while listening to the radio while navigating.
It's a waste of time trying to use it with USB or SD playing.

Same question as above, do you have RDS enabled?

Mine has been rock solid stable in all other functions, this July firmware is particularly good. It's only laggy in the specific use case (SD playback + Navigating). Never had it lock up or had to do a fuse pull though. As I said, it's responsive. if i'm listening to iPod or FM Radio. Tiny bit of lag on changing volume, but otherwise fine.

SD Playback on its own actually works really well now, even with FLACs, very very small delay changing/loading tracks, basically as you would expect any other function to work etc.

Can't remember, you two have DNS610s though, yea? Which might explain it....

[asa572]

I haven't been able to find the RDS setting since the latest update.
I figured no use looking for it to hard because it has never worked properly any way.
