Issue with sluggish premium sat nav

Recommended Posts

Hi

I have been experiencing a rather sluggish ML premium Sat Nav and would like some help to try and sort it out. I am sure we would agree the infotainment system isn't one of the fastest but the leisurely pace I have been experiencing is very frustrating. Symptoms started ~6 months ago.

When trying to make phone calls, on occasion, the system is incredibly slow.  I have noticed that it is also sluggish performing other functions, but it is the phone that is most annoying to me. It can take around 1 minute to register that I have pressed the call button either via steering wheel controls or using the remote touch. It's almost like it is doing something in the background. Interestingly, the fault doesn't happen as soon as I have started the car but it can happen say 20 minutes into a journey. Another symptom is that it is random and sometimes the system works as it should.

I have tried everything to try and sort this annoying issue out i.e. turning off WI-FI access etc, resetting the Bluetooth phone connection but nothing seems to work. I have tried to see if there is a way to reset the system back to factory settings but can't find a way to do this. 

Any ideas greatly received:taz:

Try restarting the NAV system by holding down the ON/Off/Volume button on the centre console with the hybrid system in the ready state.

Certainly not normal - mine is almost instantaneous.....almost

I think you may need a software update. These issues happened on earlier vehicles, especially 2014 but were fixed with software updates throughout the years.

You may be lucky as I expect you're out of warranty to go to your dealers - otherwise, a cheaper option would be to get the latest map update for the nav system from an online seller as it comes with a software update I believe.

I noticed an sd card yesterday for 35 quid. Worth a shot if it includes this car. I paid 65 for mine.

Update the software. My 2015 was a big sluggish at times before i updated. Now it's a lot faster.

I bought new maps on sd card from a website and that updated the software for me.
