Never got much use really. I bought a trucknan with built in dashcsm so this Garmin 55 lived in the cupboard. Having a clear out of unwanted belongings. zThis dashcsm is fully working and has a micro SIM slot. Use your own micro SIM. Old magnetic fixings disk to windscreen, not included,! I use self adhesive tape on a suitable size steel washer. That works just as good or buy a cheap one off eBay.
This product would be a great fit for those who have already installed a new satnav in their car and do not need a separate dashcam.
