Disconnecting the battery

My Satnav, DVD player, USB and phone pairing has stopped working.
Dab, tv and radio is still working.
I've tried turning the engine off leaving it over night to reset but no luck.
I was thinking of disconnecting the battery to reset the system that way.
I have the tyre monitoring system, so I was wondering if it would be safe just to disconnect and reconnect or would it be buggering other systems up if I did so?
Many thanks

RE: Disconnecting the battery

Easiest way to fix it is to call out LRA! They will reset the Battery Management System for you too

A Pangea Green New Defender 110 First Edition is now sitting on my drive alongside British Racing Green Electric Mini Cooper SE Level 3. After 21 years in my hands my TDI300 90 was handed on to the next custodian on 15 July 2022.

RE: Disconnecting the battery

Interesting LR assistance are coming out for something trivial like that. It wouldn't have surprised me if they told you to contact the dealer, it's not like you are stranded or anything.

When my battery failed and LRA did come out because I was stranded, the guy replaced the battery without any problems. There was an assortment of error messages which cleared after a few seconds though it might take a few miles of driving to completely settle.

Evoque was great, now in an RRS SVR

RE: Disconnecting the battery

Just a quick update for forum members.

LRA came out and disconnected the 2 battery terminals for about 1 minute, the system reset itself and all was working ok again, the techie told me that this should cure the problem most of the time, the infotainment gets a bit cuffuffled now and again. Disconnecting the battery causes no problems with any of the other systems.
Once reset all you need to do is check every thing is ok and reset ur clock.
All in all took 5 minutes, it took longer to fill in the paperwork!
Tnx all

Glad it all ended up fine and without a trip to a service bay.
