I purchased a 1030 unit 18 months ago, used it 4 times as I couldn’t download routes, last used it in October 2020, went to use it again on 7-11-20 so left it on charge the night before as it was flat. Next morning it wouldn’t start, so I left it on charge for the morning. Lucky I was at home as I was alerted by the smell of burning to find the charging adapter was burnt out and melted. I only use official chargers so it appears the unit is insufficient and shouldn’t be on the market. DONT LEAVE THESE UNITS ON CHARGE UNATTENDED!
