Hi all, im new here, and i was hoping to get some advice. I recently brought a Tomtom go 740 live, after my 720t broke. The green light on the top is constantly on, except when it turns orange when plugged in. Is this normal, that even when you turn it off, the green light stays on? The battery dosent hold charge very well, and ive just changed the battery, but nothings changed. Ive left it charging through USB all day, and when i switch it on, it lasts about 10 secs and goes off. Thanks in advance for any help you guys can give.
