W211 gps fault

[sheepwolf]

Hi all,

Just bought a 2004 w211 e320 and having a few niggles.

My Nav / GPS is playing up. My location is showing that I'm out at sea and from my understanding the Comand setting to change date and time is linked to the GPS ie. with GPS & nav enabled systems you can't manually set the date or time accurately.

Im not sure if i need a new updated disk & firmware update or a new GPS Antenna.

So I'm thinking of replacing the GPS antenna with something like this:

or this:

https://www.commandonline.co.uk/generic_gps_antenna.html

I was wondering if anyone could offer any advice on the route to take and if anyone had a diagram or instructions on how and where to connect the antenna / if i could install it in the boot area without disassembling the tailgate.

I was hoping to unplug the current gps cable and insert the new / place in a hiden spot near the dvd or fuse box.

On another note, was wondering if anyone has an experience upgrading the firmware for Comand and if this is good idea or risky and what you achieve by doing this ie. more options / settings unlocked or is it just better to not muck around if its woking fine the way it is?

Many thanks,
Wade

Sorry I can’t help with your issue but there are some bright sparks on here (get it?)

You are best off with a genuine GPS antenna. Changing it is straight forward and should resolve your positioning issues.

If you buy a genuine Navigation disk from a reputable seller then it will have the necessary navigation firmware on it which will be loaded first time you insert the disk. You wont get any updated features though, just bug fixes.

Thanks for your responses guys!

try and buy a fakra one off ebay , fitting is pretty easy on the left side of the boot , when you remove the inner liner. you can punch / drill a small hole in the parcel shelf and stick the unit to the rear window as i did , and feed the wire down , just be wary of the wire and not to foul the boot opening spring/mechanism .

You can download and burn a firmware update to cd from the comand website.

The GPS antenna in the first post is the one I bought and installed in my E55. It's not difficult and I put mine on the rear parcel shelf. Just unplug the old fakra connection and tie it back with a cable tie. Its not worth removing IMO.

This is the thread I made when I changed mine with a few photos that may help.
