Hi first post here and unfortunately not a happy one!
I am a second owner of a 2005 Navman Trackfishh 6600
and am very happy with the unit performance wise but recently
when the unit warms up the screen light starts to pulsate
turn it off and on and its ok for a while then starts again
Any thoughts and whats with the warranty on these units? :(

cheers Frank

Mate, I have a 6600 also and mine does exactly the same. I find it does it after starting the boat with the unit turned on mostly. Bloody anoying. Thats 2 of us, 3 more and we can take out a class action against Navman.lol.Warranty is 12 months I believe. I am going to go a different power source or some sort of in line power regulator to see if it will stop it. I dont recomend calling Navman in Sydney though. I called last week and went str8 into a "waiting line" for 19 minutes. No 1300 or 1800 number and no customer service. Didnt even get to talk to a human.
I will let you know how the power eg works, if at all.

I think a regulator is a great idea, a mate of mine with a Navman (not sure of model tho) had a similar issue. When he fitted a regulator the problem was fixed.
He is running a Yam 2 stroke.

Frank does your problem occur when the motor is running, or shortly after stopping the motor?

To be honest I havn't noticed.
I did replace both batteries recently to Century Marine pro 600's
And i noticed it only when the unit was warm to touch and i was
fishing for calamari so yes it would have been stop start with the motor!
Can someone please explain the regulator and it's location
I have common 12v knowledge.

Mate I dont know your unit, but with mine, in diagnostic mode, I can see what the voltage is out of the batteries and in turn the alternator.
When the motor is running flat biccy you should be able to see what this voltage is, and if it is getting up there, (15-16+V) the onboard regulator in the unit would be bustin' its arse trying to keep the voltage at the right level.
The downside to this onboard regulator doing its job, is that it will generate heat.
The extra heat, combined with what the unit and its lcd etc does anyway, could cause issues.
A regulator should be positioned in circuit prior to the batteries (from the alternator) generally.
BUT, there are a lot more issues to consider.!!!
To fix the Navman on its own, (if indeed this is the fault!) then a regulated 12Vdc supply to it only should do it.

Why not get one of those cigarette lighter regulated supplies, wire that up temporarily, see if it works???

if you see over about 14.5v the regulator in the outboard needs attention.
Adding another regulator seems pointless, especially since the specs say the input voltage is 10-32 volts DC
If anything, some noise filtering may be required.

I'm pretty sure the output is hovering somewhere around 13.2v
on both the unit and dash guage.
Does the filter need to be placed in between the unit and the fuse?
I also have all my positive input connected to a common +Lug !
Thinking back I'm sure it only happened whilst at rest but stop/start
whilst drifting,

Voltage is good.
If it happens with the motor off, forget the filter idea as the proble is not related to the motor or alternator.
Try it with any radios turned off.

Will do I installed a Noise filter today for peace of mind
and i also seperated the power supplies to all units onto a buzz bar
rather than a singular + Lug just to neaten it up a little.
So far so good but the unit hasn't really warmed up yet.
My instincts are telling me it had something to do with the constant engine stop/start whilst unit was on.
Thanks for your help
cheers Frank

just a quick coment if its not wired directly to the battery you can occur some problems mine was really tempramental as soon as i directly wired it with a inline fuse of course no problems at all fixed every thing
i used to get track and memory issues when wired through the buzz bar

Cheers Kitty cat will keep an eye on it.

P.s how do you isolate the unit if you have it connected

direct to the battery. I believe these units can still draw supply

even if switched on. i suppose it would be viable then to run it thru

a sepearte switch to isolate the unit!

Bloody long way to the battery direct from me flybridge kitty cat.lol.
I am however going to set up a new power block that is isolated from normal stuff that could have feedback and/or major draw from the block. Needs to be heavy duty feed cable. I have an invertor running from my main power feed to the flybridge so I need a seperate one anyway.
Good to see that so many have navman with same issues and there are many fixes for these.
Roll on October M&G Agnes.
