OK I have been using the BU-353 for a few months no.. it works good the prolific drivers give no trouble at all..it is OK..
now the only problem I have is that it takes some time for it to get tha sats data for tha first time.. as soon as I move the unit outside.(I have it placed near the rear windsheild) it gets the signal in a few seconds, when the unit is inside it might take as long as 5 minutes.. but as soon as it has 5-6 sats then it works ok even if i put it back inside .. has anyone tried to make an antenna for it.. or better try to keep it powered up so it would never loose the sat data??!!
i don't know if it will work but, using batteries (lithium rechargable) along with a diode, would keep it powered for 2-3 days when not starting the car (the unit as far as I know, has built in capacitors so it would keep the data needed, but I don't know how long before they loose their voltage.
any ideas? i don't want to move the unit outside..(stolen, attracts attention, not really watrer proof..etc.)
i think it would drain my battery in 10 days or something.. i travel a lot.. and leave the car..
I just want a confirmation that powering it up all the time would solve my problem
power it down and then power it up, or cold start).
power to the PC. It has been working that way for nine months now no problems. Still using the car's factory original battery which is over four years old.
I'm not sure where I saw it, but someone made a simple board with a relay, that would apply power to the GPS unit for a few seconds every so often (maybe every 10 mins or half hour?), just enough to keep the internal cap charged. If you're into electronics, it would be a simple project with a 555 timer or small microcontroller.
But don't take it from me! here's a quote from a real, live newbie:

i see. thanks for your answers guys.. anyuone attemmpted to open the unit upp and connect an antenna?
