Question about Sony NV-U44 GPS Receiver

2 Answers

I have a Sony GPS model NV-U44. I bought this cheaper GPS after a disastrous freezing experience with a Magellan 4250 which I returned to Costco. The NV-U44 works well enough minus the bells and whistles that were in the Magellan 4250. My major complaint with the NV-U44 is that map updates seem totally unavailable unless,(as the computer screen is telling me) I update Internet Explorer to IE - 8 version. Then presumably I will be able to download map updates and install them on my GPS. I don't believe it and I'm not messing with Internet Explorer which I don't use anyway. Not being able to get a map update is one thing: Having Microsoft messing everything up is another! Seems to me that various "programs" are tripping over one another and getting more and more complicated all the time.

GPS had fallen off glass and broken power connector port( 5 pins in metal frame) inside of GPS. I can not put power jack into GPS.

From the Magellan website,, their policy on broken screens:

"Magellan will replace receivers with a broken display returned within the warranty period with a reconditioned unit of the same or comparable model at a reduced cost to customer. Customers with a broken display unit returned outside the warranty period will be given the opportunity to purchase a new unit at a reduced cost or reconditioned unit also at a reduced cost."

Magellan Maestro 4250 freezing up

I just purchased a referb from TigerDirect and the only issue I discovered was a lockup when the unit goes to sleep. Try holding down the power button for 15 seconds then release it to cycle the unit. Then hold the power button down again for 5 second to start it back up. I had to do this for my bluetooth to work and not freeze up. Now I just turn it on and off manually and avoid having it go to sleep. I also downloaded the firmware update to 4.86, you can download it from Magellan's website. My unit works great so if that doesn't work contact Magellan and I'm sure they will have a solution.

No a practical solution, but at least you will get your device repair, after being on hold for 40 minutes I spoke to a very nice rep, unfortunately evethough she didn't admit it, it seems a software problem with the new 2008/2009 map update, in other words no way to fix it, you need to send it for repair, make sure you tell them to update the device with the new 2008/2009 Maps, if not you will have the same problem later on, Good Luck
