Jack Carter Posted June 30, 2014 Share Posted June 30, 2014 (edited) Hi, Had a decent 500 mile drive over the weekend in the 370z. I had all my destinations pre saved into the Sat Nav to save time. I had a major issue on 3 or 4 occasions though with the sat nav throwing a wobbly. Exiting a motorway junction on a couple of occasions, the arrow seemed to float off the road and didn't know where I was. This was on old established junctions - not where roads have changed layout at all in years. Also on occasion, after taking a change of direction at a major junction, the arrow was running parallel with the actual road I was on (about half an inch on the screen to the side of the actual road I was on. At one motorway intersection, it caused me to go wrong when as I approached the junction I should change to, it initially showed the correct direction, but then suddenly jumped to show a different route, before the arrow just lost it's way over none existent roads... Anyone else had this ? Is there a reset procedure or anything to solve it or is it faulty ? Cheers.

Will370z Posted June 30, 2014 Share Posted June 30, 2014 Yup happens on mine now and again, occasionally signal is lost or the route planning algorithm gets a little confused Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted June 30, 2014 Author Share Posted June 30, 2014 (edited) Sorry to say it Will, but glad it's not only me then Heading from Leeds to Doncaster was downright disastrous for me. It completely cocked up when changing from M621 to M1 to M62. It just changed it's mind repeatedly. I guess there is no fix for it then. I wonder if updating the maps would help ?

alroma Posted June 30, 2014 Share Posted June 30, 2014 It's happened a couple of times with mine too - probably just a dodgy satellite signal rather than a software/maps issue. Out of interest, you could check the GPS info next time it happens and see how many satellites it's picking up? Quote Link to comment Share on other sites More sharing options...
Ebized Posted June 30, 2014 Share Posted June 30, 2014 Maybe this might help you? http://www.350z-uk.c...page__hl__discs (Need to check through the pages to see if your SN is compatible - sorry I don't know as I have the pre connect premium in mine but done the DVD upgrade for that and it is has been fine before and after) Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks for the answers lads Think I may go for an update as suggested. I did check how many satellites were being received on the one occasion and it said 8. Quote Link to comment Share on other sites More sharing options...
Will370z Posted June 30, 2014 Share Posted June 30, 2014 MIne has been updated but still does it, then again ive never seen a sat nav that is perfect in its route and maintains signal all the time Quote Link to comment Share on other sites More sharing options...
Kraziekatz1 Posted June 30, 2014 Share Posted June 30, 2014 I always have a problem when I'm near the Isle of Wight, the Sat Nav seems convinced it's in a submarine and the english channel holds no boundaries Quote Link to comment Share on other sites More sharing options...
Will370z Posted June 30, 2014 Share Posted June 30, 2014 I got annoyed with mine coming back on the M6 toll, it kept wanting me to pull off at every junction and go the long way when i had a nice clear road ahead. Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted June 30, 2014 Author Share Posted June 30, 2014 I've got used to the system in my 5 series which has never missed a beat in the UK or abroad. I think I'll still update the maps in the Z but maybe look at getting a good iphone mount so I can use the satnav on the phone as a secondary backup.

Is that because you have the "avoid toll roads" option on? Quote Link to comment Share on other sites More sharing options...

spanner Posted July 7, 2014 Share Posted July 7, 2014 Having covered 2800 miles round France in my Zed over the past fortnight with extensive use of the nav, I can confirm these "quirks". Typically, they always appear when you need it most, such as on a roundabout or approaching motorway exits. It also seems to "update" the route quite often, with the yellow one-screen route completely disappearing until it's recalculated. However, one thing I can definitely confirm is that it really doesn't help if you store one of those reflective sheets for windscreens across the boot. Seems to block the antenna almost completely!!!

I've been having radio data conncetivity issues (ie the bit that tells you whats playing) I keep a yellow reflective jacket in my boot - I wonder if thats what causing it Quote Link to comment Share on other sites More sharing options...

Jack Carter Posted July 7, 2014 Author Share Posted July 7, 2014 Ahhh. Where is the Sat Nav antenna then ? Reason I ask is that when I was having the issues last week, the boot was jam packed at the time. On top of all the luggage was my jacket which oddly enough, does have reflective strips on it. It's funny as I have had long journeys with the boot empty(ish) and the Sat Nav was faultless Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted July 7, 2014 Author Share Posted July 7, 2014 RIght. Don't think it's anything to do with what's in the boot as the GPS antenna is under the nearside dashboard I think - so the link between my empty boot space and a fault free nav experience were clutching at straws.
