About every 2 minutes my 5045 "restarts to improve efficiency" making use of it impossible.

I was recently asking myself the same question when I was searching for a reliable joiner in Edinburgh to help me with some home improvements. Some qualities I looked for in my joiner were:

- Efficiency
When it comes to completing home improvement projects, efficiency is very important, as you want to make sure that things are done quickly and effectively. I worked with a company called B&M Joiners & Building Services and they offered great turnaround times and were timely with their responses to my queries, which I think is really important.

- Price
You don't want to pay too much or too little for your joinery services. If you think your price is too high, you should look elsewhere. As well as this, super low prices can also be a red flag so you should try to avoid any quotes that seem too good to be true.

try to reprogram your device..or restore to default.

thanks :D

Best thing to do is throw it away and get a different brand!

I had exact same 'Magellan 5045 frozen' problem. Here is how I fixed it. Go to www.magellangps.com/contentmanager. Download and install Magellan Content Manager. Plug in your GPS. If content manager does not activate automatically, start it manually, like any other windows program or by right clicking on its icon. You will be asked to register your device and its serial number, etc.
After registering, if Content Manager fails to take you directly to the download location for your device, along the top of the Magellan web pages you will see a set of tabs, one of those is 'Support'. This is a pull-down menu. Select Manuals and Software update. This then takes you to their 'Support' web page. On the support web page, click on the 'Manuals and Software Downloads' button. This will take you to a page where you will be asked to select from four Download Categories. For the roadmate 5045 and similar gps intended to be used in an auto, select 'Magellan Vehicle Navigation'. This will take you to another page where you will have to select from three product series. For the 5045 series, select 'Roadmate Series'. This is another pulldown where you will have to select your product number, e.g., Roadmate 5045. This will finally take you to a page where you can select software and map updates. You will have to connect your Roadmate gps to your computer via USB and you will have to register. It is confusing because you will get incorrect and irrelevant statements like your device failed to register. It is somewhat quirky but if you follow the instructions and you have a wideband cable or FIOS internet connection, the upgrade to the software and the maps takes about 30 minutes. Do unplug your RoadMate from the USB unless asked to do so by the Content Manager program. After the software and maps update, the Roadmate 5045 worked like better than new for me.

I have the factory PDF service manual for this model. Ibm/Lenovo SMs are basically impossible to find. They are very detailed, show assembly and disassebly and have specs and diagrams. I don't have a download link for you

Try doing a "factory reset". This will "burp the baby". Turn the set on and ignore what you see. From the side control panel, push the volume+ and channel+ buttons in synch. This will take you to a base OSD (on-screen display) that can best be compared to the BIOS on your PC. The real goodies are here.

On the OSD, you'll see "picture", "audio", and "advance". Using standard navigational input on the remote, go to "advance". Tab down to "clear all". The set will appear to turn off, but the front LED will remain blue. The set is re-formatting the on-board memory and will restart in a few seconds.

Your panel should now restart as normal, but will be returned to factory "burn-in defaults". Your color and audio adjustments will be lost, so you'll have to do some fine-tuning in the regular OSD menu. Cycle power to the TV after you have made the desired adjustments.

TIP: Perform the factory re-set a second time, then select "picture". Toggle down to "video format". You might find it set to "Pal". Change this, using standard navigational input on the remote, to "NTCS" or "AUTO". Cycle power to the TV after you have made the desired adjustments. The TV will now perform at a refresh rate of 60hz, the American standard. "Pal" is 50hz, the EU and Asian standard. The improvement to image quality will be noticable very soon, as both your eyes and the set adapt to 9.94 hz improvement. NOTE: You may need to fine-tune the TV again after making this change.

Go over your cdoe make sure you don't use unnecessery commands, joins and loops.

Making your code more efficiant is a thing you'll get better with the more experianced you get.

Cheers.
