E46 Mk4 Maps and upgrade question
 

Hi, I'm a total newbie to this, so apologies in advance for that!

Just just bought a 2002 BMW 3-Series with built in navigation. I know the maps are old, but I'm not sure how old, as some major motorways here in the UK were missing when I drove it home.

THe system is the Mk4 as it has the large 16:9 screen, and a DVD logo on the drive unit in the boot. Oddly there is a CDR disc in there so I guess the previous owner had a copy of CD maps?

Ive a few questions if possible...

I have read that there are new versions out there that add a new isometric view with a background, and night mode amongst other things. I downloaded this (the file was called V32) and burned it to a CD but nothing seems to have changed. It definitely looked like it updated, as I got the message on screen, and the progress bar, then it restarted - but I dont see anything new, and no mention of new "views" etc. - is this due to my outdated maps? The top right of the screen reads "SW 4-1/00" is this up to date, or not?

I have looked around for some maps to try online, but they all seem to be around 6GB, so do I need to use a DVD9 disc? (I dont have any)

I found one called "BMW Professional 2010" which burned and fitted on a disc, but the system wont accept it. How can I tell which maps will work with my E46 please? Does anybody have a link to some recent UK / GB maps that will fit on a 4.7GB DVD?

I dont get any reference to post code navigation, and I;m not sure the TMC is doing anything (it shows TMC in red) - again is this because of my old maps, or is there an issue with old firmware?

Many thanks in advance.

I think you have to hold down the MENU button to get split screen, and on DVD maps, 3D view.

4-1/00 is the last version of the OS.

TMC is only broadcast on Classic FM, but you should have twin tuners. Set the radio to Classic and see if the TMS goes green.

7 digit postcode and night mode is a hack, search for those.

Enter the postcode into the city field.

For maps, pirated maps are not allowed to be discussed on the forum.

DP: Sometimes the MK4 DVD laser can pack up, leaving only th CD laser functioning. Something to bear in mind before splurging £100+ on a disc.

Here is a thread that explains how to enable the perspective view. You have to go in to the service menu to enable it there. Then you can select the option from the regular map view.

Night Mode is a modification to the nav OS. There are links to that in the sticky post at the top of the forum.

When purchasing new maps, you need the "High" version, not the "Professional" version. Here in the US they can be purchased directly from the map supplier (formerly Navteq, now TeleAtlas) or from the dealer. Which has the best deal depends on discounts offered (here, many dealers offer a discount for BMW club members).

We also don't have TMC here, but I believe you need a disc with some sort of TMC enabling key on it.

You can run into problems with a very mismatched map and OS, because some combinations were not tested (new OS, ancient map) or impossible to test (new map, old OS). I have seen odd behavior with the new OS / old map combination - routes were very sub-optimal.

By the way, here in the US we didn't get DVD navigation until the 2003 model year (September 2002 production dates onward.
