Complaint / review text:
Magellan Roadmate 5045-LM is junk! All they want is to make you buy another one! I don't own the unit, but I've had to help my friend as I am an electronic technician. At first glance all it needs is mini USB port because the battery was completely drained and the unit is not turning on - pure and clear. So, I found similar mini USB jack on eBay.com and installed it, then I plugged it in to the wall charger and tried to turn it on, the unit just makes an attempt and then it died. Then I think that the battery was deeply discharged I let it charge as per manual for 4 hours. After that I've got about 4-5 minutes running and GPS returned a message that battery is low and unit goes off while still plugged to the wall charger (again as per manual 2.0 Amps 5 V DC).
As I am getting curious of what is going on, I got some measurements with my Fluke and realized that the battery is not actually charging while unit is on and plugged to the charger even though it shows on the screen that the battery is being charged. As we talking about Lithium battery I was sure that original battery is bad I ordered new one and give it 6 hours charge before turning unit on. Now on the new battery alone unit runs for about 2 hours (plus minus few minutes) but when plugged in it still drains battery instead of charging it and providing enough power for the unit. Last experiment was with fully charged battery and charger - all I've got is about 3 and a half hours. After analyzing hundreds of customers reviews and complains about battery lasting for 1 to 2 years and bad mini USB connectors (I suspect they where DESTROYED because of this problem) I can say why - that is either firmware if it controls battery charge or some stupid engineer designed this unit or it was a conspiracy to sell them like a hotcakes!
