I used these folks, extremely helpful in all respects .. Satnavishop.co.uk worth a check of the website and maybe a phone call !

I used Satnavishop.co.uk to update my 2014 A6 allroad with 3G+ MMI. "David" was extremely helpful, answered every "help" email within an hour, and they sorted all the hiccups easily. Hiccups were unusual, it seems, as some other work had resulted in some of the MMI already being updated, but no-one knew... least of all me. !!

Might not be relevant at all, but a similar problem (heat one side cold the other) on a different car was also caused by a partially blocked matrix. It seems that a partial blockage allows a very low flow that provides a bit of hot water to give heat to one side, but once thats gone the "other" side only has lukewarm/cold water flow, so generates no heat at the vents. Replacing the matrix with a "freeflowing" one solves the problem as both sides get plenty of hot water. Hope that helps, although I accept it might not !!

Hi memzey, antenna is placed front right hand corner of dash just beside the speaker grill (1.jpg). Cable goes down the right hand side, then in behind the fuse box cover,(2.jpg) then out and under the steering wheel area with excess cable pushed into the large recess, (3.jpg) cable then goes up and over, tucked in between the fascia and the steering wheel and into the MMI. I simple connected to the MMI then reseated the MMI with the cable coming out of the top right corner.(4.jpg) Not ideal in any way but it works. Car is booked in to a local auto electrician to have a new aerial fitted the week after next. The SRS warning light is apparently caused simply by having to unplug the two cables underneath the MMI in order to get sufficient access to the aerial socket. Simple reset with the appropriate kit sorted that.

Quick update folowing the weekends efforts. On Saturday I removed the MMI again and found a way to re-route the generic aerials cable such that, although not perfect it is out of the way and the aerial is at the bottom edge of the windscreen. Satnav has worked perfectly with 8/9/10 satellites when ever checked. At least this proves its the existing aerial that is the problem. Along with memzey I also still have the airbag light now on since I started this saga. I don't have a code reader so the car is booked in to a local non-audi specalist for next week. They will check out and fix the airbag problem, and advise me on their cost of fixing the satnav aerial properly. I know I've got it working with the bodge, but I like things done properly.....

Progress, of sorts..... using the second video above (thanks Alpha Omega) and the purchased tools, I successfully, eventually, gained access to the rear of the MMI. The cables are very short and a couple have to be unclipped to get to the back. Plugged in a generic GPS aerial off ebay (less the £5.00!!) and it all started working, 9/10 satellies received... happy me .. or so I thought...... I couldn't work out/see any way to mount the aerial near the windscreen, so simply placed it on top of the MMI. Then had some "fun" getting it all back together..... there is VERY little room and the numerous cables conspire to prevent easy access/movement ... but got there eventually. Test drove it and it was VERY erratic, quick check and only 3/4 satellites... so obviously on top of the MMI is useless. Another days work I guess trying to find a better place/way, but at least I know how to gain access. To add to my woes, the "safety systems" warning is now illuminated... I wonder if the repeated moving of the seat and kneeling on it to try and get a torch/eyesight into the MMI area has damaged something, a very quick look doesn't show any loose connections, again something for another day ... ......at 72 my arthiritus, bad back, eyesight and patience have all run short for today !

OK, from memory as the car isn't here at the moment..... with no route planned, select "Tour", then select the topline, regardless of what it says, press centre button, rotate centre button one click clockwise. Should now display number of satellites and assumed position .. in my case "0" and south wales-ish even though I'm 80 odd miles from there !!

That looks a possibility, thank you, appreciate the help. Hopefully these tools will be man enough to do the job !! 12 Heavy Duty Car Trim Removal Set Radio Panel Door Dash Vehicle Repair Pry Clip 7427274231726 | eBay

Found an article that says the MMI is held in by one screw that is accessible after the climate control panel is removed....... but doesn't tell me how to remove the climate control panel ..... any one able to assist ?

Thank you for your efforts, but mine doesn't look quite like that, and certainly does NOT have those two little cutouts. Hopefully someone can offer other ideas!!

2014 A6 allroad and the satnav has just started misbehaving. Internet search has enabled me to find a way of knowing that 0 satellites are being received, so I suspect the sharks fin aerial has failed. I don't think its simply moisture as its been bone dry for 10 days and the car is black and has been stood in the sun, so the roof has got pretty hot!! Seems that is a real PIA to replace as the whole headlining has to be removed. Several sources state that unplugging the existing GPS aerial and replacing with a generic GPS aerial from fleabay is a simple and effective solution .... only problem is I can find no detailed instructions on how to remove the MMI to do such a thing !! There are various mentions of special tools and/or dismantling centre consol and others say its simple just one bolt !! So what is the truth please !! Could someone who "knows" give me a detailed guide to the easiest way of accessing the GPS plug on the MMI so I can then fit a replacement GPS aerial. Any ideas greatly appreciated.

I presently run 255/40 R20 at 37psi all round as the car is mainly used to tow the tin-tent, so has a fair bit of tail weight as well as a load of kit in the back, its very stable. The previous owner, who purchased the car new, paid an absolute fortune for the 20" wheels - OK they look good, no dispute there - and I put new tyres on when I bought the car. Those tyres are now reaching time to be replaced, and I'm very seriously considering buying some 18" wheels and running on 235/55 R18 tyres, as I think the ride on 20" wheels on the abysmal roads round here is back breaking - literally!!! The car is a dream to ride in cruising the motorways, but a country road with deep potholes...... not good at all 😞 Trying to work out the relative costs of buying a set of Audi 18" wheels off the Bay, and how much I might get for my 20" ones. There appears to be no to little difference in the actual price of the tyres (Continental SC5).
