I have a pretty weird problem with the relationship between my Tom Tom and the smart key on my 2010 TDV6. If I have the smart key anywhere close to where the Tom Tom is plugged in via the front power supply (cigar lighter) I get a smart key not found warning and the car won't start. If I unplug the Tom Tom then all is OK and I can plug the Tom Tom back in once the car is started. Has anyone had anything similar happen.

Was at a horse trials yesterday and three RRS were recovered by Rescue. The car park had power lines running over the field and wouldn't start. Once towed to the gate and out from under the overhead lines, they all started. My normal key worked fine so fair assumption is that obviously smart keys are easily upset by electric current. Another own goal by LR.  2x TDV6. SE and HSE. Both returned to sender with issues👀

dont worry its not just lr smart keys at work in iraq we had landcrusiers that we couldn't start of we were close to the gate of the camp due to electronic countermeasures on the perimeter 50 yards down the road no problems and had the same problems at a power station only the dead truely know peace,
Bootneck its not a job its a way of life!

Not had that problem with my Tom Tom (710), which I use on long distances as a camera detector, but sometimes my car won't start or even light up the dashboard outside a friends house, I am sure there is a mobile phone mast nearby which causes interference

The Tom-Tom is interfering with the signal from the key, as will the power lines etc.

It is either directly interfering (transmitting on the same radio channel) or generating strong interference which is de-sensitising the key system.

if this is the case I believe you can hold the key fob up to the bottom of the steering column plastic cover and this should get around the issue. 2016 RRS 4.4 TDV8 Autobiography Dynamic in Montalcino Red and Stealth Kit

The workaround I use is just to disconnect the Tom Tom from the power source, start the car and reconnect the Tom Tom or move the key further away from the power source for the Tom Tom and then start the car. Thanks for the interesting comments though. I have to say it was a bit of a shock when on the first morning I had the car it wouldn't start until I figured out it was connected to the Tom Tom. Also if the built in Sat Nav didn't keep trying to put me on magical mystery tours to get from A to B via X, Y and Z I wouldn't need the Tom Tom

I find the 2012 version of the RRS sat nav far better than the 2007 version.

I even found out today that the 2012 version learns your (bad) habits.

I regularly travel from Reading to Norwich, I know the route well but I always use the sat nav so that it gives me traffic information and "time to destination", however as I know the way I ignore the route it offers.

About half way I divert from the route to a cafe for breakfast, and I do this everytime and its about a quarter of a mile off-route.

I noticed this morning that the sat-nav has now, without prompting, included the cafe as a waypoint on the route and directs me straight there, spooky! 2016 RRS 4.4 TDV8 Autobiography Dynamic in Montalcino Red and Stealth Kit

Yes, there are a few routes that I do regularly that I know better (going to the inlaws for instance) and I noticed that it's learnt the routes that I have taken.
I like you use the satnav for traffic and time to destination. ON THE WAY: BMW F21 M140i

Maybe they should call it the "not so smart key"

Yes the 2012 on system learns routes, has easy route can adjust for traffic etc.

The key problem isnt new - Discovery keyfobs have had this problem in certain areas for years...the sweet spot is under the steering wheel as mentioned...how weak is your battery? Mike
