You have a poor signal G. Not sure where you antenna is but it needs attention.
Ray.
Not necessarily. New roads are built but satnav maps are not automatically updated.
Certainly my 2018 car is happy driving through fields around the north of Norwich because the multi-million pound road (opened in 2017) doesn't feature on the satnav and I'm not paying to have it updated, because most (all, so far) of my journies have been along well-known routes. HOWEVER, whilst "rushing" to Norwich Crematorium, I discovered that a road through a housing estate was now blocked by the bypass and I had to make a very seat-of-the-pants diversion: could have been awkward!
I regularly update the TomTom (free lifetime updates) for the motorhome, given the potential for problems with bridges etc, especially abroad. I'm thinking of transferring it to the car in the same way that the dashcam moves between them.
For years I've had problems with friends and delivery drivers getting to the village green and then asking for directions to my house. I couldn't understand why. Eventually, instead of "knowing" where I live, I entered my post code into TT and it took me to the village green. It took me almost 3y to get TT to acknowledge that I knew where my house was: screen shots from Google, Garmin etc who had it correct were ignored. However, I accused them of potentially starving vulnerable OAPs when Lockdown started and supermarket deliveries couldn't get to us: suddenly my house was HERE! Sadly, many companies have TT-based devices and if they don't pay to update them then they still go to the green.
We didn't have this problem when we had to balance an OS map on our laps and remember instructions to take the second right after passing the pub!
