Holux GPSlim240 - GPS receiver module
it is really a great product when it is brand new. BUt problems come out after a period of time. The cigarette charger was defective at the time it arrived. The batter died after 11 months so you have to connect it to either the computer or a outlet for power for it to be working.     I rarely used it, only about 10 times in the 11 months. The worst thing is tha its warranty worthes nothing. Not even an address is provided for your to get it fixed. And its manufacturer's website lists address out of US, no
