Hi
I have a 2012 E Class Cabriolet which I am pretty sure has a NTG 4.5. The DAB reception is unusable - it drops out after after a few seconds / minutes - and I am getting fed up with just listening to Radio 2 on FM after two years. Having looked on the forums I am aware that this was a very common problem.
I understand that's there a firmware update available which was supposed to address this issue. Also there's some suggestion that it also updated the ventilation control which can go a bit haywire when left on Auto on a cold day with the top down - I get really toasty feet if I don't remember to set it all manually).
My questions are:
1. is there anyway of checking whether or not the firmware has been updated myself. The previous two owners didn't take it to main dealers - so I suspect that it hasn't been.
2. if not, do I have to take it to a main dealer? How much are they likely to charge for a check and for an update? Or could it be a local Merc indy - one of whom has the STAR system. I have just had them service the car - but I forgot to ask them about the DAB (and they weren't particularly cheap either although seemed good).
3. if I do pay to get the firmware updated, any thoughts about how likely is this to resolve the issue? There seems to be a bit of mixed opinion on the posts that I have read, but it is a bit confusing as there seems to have been two updates with the first one not working very well.
4. if it doesn't work then presumably I need a new DAB Antenna or is it just the DAB Amplifier ?(I have read that some Mercs had the wrong one fitted originally or configured to the wrong band). Will I need this firmware update even with a new antenna? Should I get the Merc one or can I use an after market one (if so, any recommendations)? Can I fit this myself or am I better off leaving it to the local car audio shop who hopefully know what they are doing and presumably won't charge me much more than the firmware update.
I don't want to spend megabucks on what is an irritation - but an getting fed up of Sara Cox.
Many thanks in advance
