Yes one year and a few days after I bought the Garmin i3 satnav unit, it’s effectively knackered.
The USB connector is also the port for charging the unit on the move and unfortunately the connector is only located by four tiny soldered points and as it’s plugged in when in the car and then out to remove it for security and then plugged in to update the Points of Interest (speed camera locations, for example), etc. (repeat ad infinitum).
The trouble with that is that – as in my case – the connector eventually gives way as it did for me on 2nd September and the unit cannot then be updated or charged, so I ended up spending a fortune on batteries on a recent round trip to Scotland.
It’s a real pity as the unit was fabulous.
