UK-POLOS.NET - THE VW Polo Forum

Right, I've been thinking for a while about fitting a VW navigation unit to my car. I've got a Navigon at the moment, but it sometimes takes so long to get a location fix that I usually manage to get to the destination without any guidance at all! I'd prefer to keep it OEM, so I've been looking at the MCD and the MFD systems, and I've been offered a pretty cheap MCD unit from a mate. I'm basically looking for advice from anyone with experience of these systems, and any help would be appreciated.

1) From what I understand, both systems use ISO connectors instead of the quadlock present on the 9N3. However, I know that the MCD was offered as an option on the 9N3 from the factory. Is this a different unit with a quadlock connector, or is the wiring loom modified to have ISO connectors in 9N3's with this option fitted?



2) From photos of the MCD wiring diagram (above) it appears that blocks A and B are ISO terminals, and that C is for a CD changer etc. I'm having trouble finding the purpose of block D. Is it necessary for operation of the unit or is it to allow the unit to communicate with the digital screen present in the dash cluster of some cars (like Golfs)?

3) Is there any improvement in sound quality with the MCD over the standard RCD200? I'm tempted to just fit it as a radio upgrade lol.

Thanks in advance

I have nav standard in mine

be aware that you need the nav cd befroe it does anything. if you dont have that then dont bother because they are acouple of hundred pounds.

Apparently its got a navigation cd included, so I should be ok on that front. Couple of hundred pounds though!? Didn't realise they were so expensive

Whats it like to use? I know it hasn't got full mapping etc, but in terms of things like guidance and ease of use?

Yeah they arent cheap!

Umm, to be honest if i had to pay for it then i would be pissed off. it came with the car but i wouldnt pay for it to be retro fitted if you know what i mean?

I dont use it coz it annoys me so i use my tom tom instead which is unbeatable.


Just to let you know as well my polo has got a different ariel at the back of the car to others, its got lkike a small black base at the bottom of ariel. apparently thats part of the GPS so you may need to look into having that put in as well?

Hmmm, think I'll give it a miss then, wait for a cheap MFD to come up on ebay or something. There doesn't seem much point in fitting something that I'll probably never use lol.

Chris - Thanks for the advice mate. Really appreciate your help
