DVD nav is rubbish

I specced the A6 to include DVD Nav and to be honest I really wish I hadn't bothered. Things I hate about it.

Routing is illogical - it would rather do an additional 10 miles distance on a motorway when compared to a freely moving a road over a distance of 25 miles. I have been caught out a few times following it's advice! EEK2.GIF

There is no selectable route (with the RNSE units fitted to the A4/3 you may select alternative routes if they are available by turning the selector knob - very useful IMHO 169144-ok.gif) - Not present on the A6 smashfreakB.gif

I also don't like the way it wont take the full postcode.... it misses off the last digit. This means if someone just gives you there house number and postcode you won't be able to easily navigate there smashfreakB.gif

The good bits are that it retains TMC functionality, and has a handy TP timer for traffic reports, and is well integrated with the car's controls and DIS.

But unfortunately I think I would rather have a TomTom for the extra cash it cost, then at least I can upload speed camera locations 169144-ok.gif

So in summary if you are thinking of speccing DVD Nav, personally I wouldn't bother, other than to offer a decent residual on the car at the end of term, instead keep your hard earned and go for a decent tomtom unit 169144-ok.gif

But doesn't it display a list of available roads/streets once you've entered the partial postcode? My DVD nav does this and it's never not worked.

Even though it takes the full postcode, my TomTom often just says 'Unnamed road'. ROLLEY~14.GIF

BMW Nav is far more "interesting" - I've had calculations of 185 miles from Warwick to Lincoln, 235 miles to Brighton, and at the weekend it took me through a town, up some A roads and then through some villages to join the A46 4 miles east of where I live. yelrotflmao.gif

It frequently tells you to go somewhere, then changes its mind and shows you a U turn. confused.gif

The best bit is the perspective view you can enable with clouds etc. Thats quite good for trying to see where the feck you are as it sends you down a one way 1 in 2 hill into a cul de sac in Shropshire. 169144-ok.gif

Tom Tom was far better. Good job it is still in the cupboard. grin.gif

You are quiet right. Audi Nav can only get you four miles away from my house and as there is no road name, it is quiet useless. Tom Tom far better- where is the cheapest place I can get one?

I'm on an unnamed track but you get there by specifiying longitude/lattitude. thats in RNS/E too though and as dansky said, the selectable route thingy is fab!

I think its a great nav system (RNS/E) but would love POIs. if they put this new mmi version of the nav in the new A4/A5s then its another reason not to buy one it seems..grrr

I was going down the M77 from Glasgow to Ayr recently and my BMW nav went ape as the disc pre-dates the new road. It showed me driving through the fields with my distance to destination bouncing between 30 miles and 190 miles (ish). Got me there though.

At least the BMW system does not mute the radio appreciably. On Land Rover systems its a real pain when the voice prompts come in when you are listening to the news. Can't remember how good/bad Audi is in this respect.

Funnily enough the postie is ok but parcelforce struggle. Worse still, TNT drove an hour to get to me, knocked on the door and by the time I got there he had dropped a card and legged it only, of course, to have to come back a couple of days later. Maybe I need a dog.

I had an A6 loaner with Nav. I had booked us into the Midland hotel in Manchester which was fortuitously a POI or whatever they're called in Nav. After taking miles out of the way down some B roads, Nav dumped me in the middle of a council estate 4 miles outside the city centre. It was adamant that I was actually at the hotel but, sadly, it was talking right out of its arse.

Let me guess ... when they finally got it to you, rather than the specialist publications you were expecting it was a coouple of CDs with some kind of database on them ...

There must be a way of re-calibrating it's start point so it knows where it is.

It uses a combination of GPS and the input from the abs wheel speed sensors. If you take the car out for a spin in the snow, it will trow out your nav by the amounbt of slipage it has seen.

It shouldn't. GPS location is absolute and car sensor info is used to interpolate based on last good GPS position. GPS should update every few seconds...

If the nav isn't recalibrating due to updated GPS location, then you're not getting a GPS update frequently enough - check how many satellites it can see.
