So, yesterday I had the little book/update icon appear on the navigation screen. I had a USB stick, which I formatted and put in the port.. pressed the update icon and it transferred the info to the stick successfully. I followed the instructional video, and downloaded the Garmin express set up on my laptop. Bunged the USB stick in and followed the prompts (add device etc). It took approx 1 hour 30 mins to successfully load the new Europe 2024 map to the stick. I then put the USB stick in the car's port, went to the Nav's settings and set up the install.. again following the video instructions. After driving around for approx 30 mins, the system told me the updates had successfully downloaded and I could remove the USB stick. The system does now show a map at the top of the list, Europe 2024. The Nav page does look slightly different, but appeared to be working fine. Satellites were sending the signal, the correct streets/roads were appearing correctly and my little car symbol was moving along the road as usual. However..
Today I made a journey to Cranwell, which is about 40 miles from my home. I knew roughly where I was going, so didn't really need to set the Nav until I got near Lincoln. This was the first thing I knew something was wrong. When I tried to key in the destination's postcode, the keypad would freeze after the first letter and a buffering symbol would appear. It wouldn't allow me to complete the postcode. Then the Nav would shut down and the screen revert to the home page. Nothing I did would allow me to input past the first letter of a postcode. Funnily enough though, if I went to the favourites/home destination, it would input my home address and give me directions... albeit with no audible instruction. I am currently reformatting the stick and downloading the update/map again. Will be interesting to see if I can install the map again and what happens again.
