[MTCB Android Head Units Q&A] TooBusy:
When you first installed TT, was it on Android 4.2.2? TT installs to a different location depending on the Android version. I can't believe it installed to external SD on Android 4.4.4.

I initially tried to install TT maps on "GPS" card because it seemed the most logical place for maps. I couldn't do it, so I searched the net, found many solutions that worked for some, but never for everyone. I tried some of them, but they didn't work for me. Eventually, I decided that the best option for me is to leave the maps on internal sd. They are only 350 MB, so plenty of space left, and it might be even faster and more reliable than on external sd (maybe not).

Yes, the problem 'should never have happened in the first place', TT could and should do better, like others, but unfortunately they don't, their support is next to non-existent, and TT forum don't even let people post solutions that are "not supported", like using rooted rom, etc, even though it could help people use their, otherwise useless, purchased TT. Understandably, there are more and more people who feel like you.

Sorry, but you are wrong on this. After I flash rom, I install TT from a backed-up apk, copy backed-up maps to internal sd where TT expects it, make sure that I have Internet connection, add Google account, sync it and make sure that Google Play is up to date (it is on [MENTION=853627]coudu[/MENTION]'s rom). When I start TT for the first time, of course it needs Internet connection and verifies that I have purchased app. After the initial setup, I may not have Internet connection for days, but I use TT and it never asks for Internet connection.

I would recommend to you another alternate solution for TT, before another alternate Navigation software: Folder Mount app. It was mentioned before, but you probably haven't tried. I haven't tried it myself; I don't need it. Yes, it has a small problem: if you switch off the unit while TT is running, after restarting, TT will start before the folders are linked and it won't find maps; so you have to exit TT, wait a bit, and start TT again. From my point of view, this is a very small problem. You paid for the app, why waste it.

[MENTION=6041319]dsa8310[/MENTION]'s solution obviously works for some people. I never tried it. I don't know what lsd command does. I thought it's like path in Windows or map search drive in Netware, but it can't be - they are used by OS looking for programs, not when a program is looking for it's data.

[MENTION=853627]coudu[/MENTION]'s rom creates 3.66 GB (I think) internal sd partition. If your maps are 2.7 GB, there is still 0.96 GB left. In original rom, the partition is even larger, about 5 GB. Also, there are new units with 16 GB, instead of 8 GB internal memory. I know this doesn't help you, but if you had one of these units, would you still bother moving maps to external sd?

Every good thing comes to an end. I enjoyed it, and I think others will find it useful too.

Nothing is best for everyone. I initially used iGo because it was installed on my unit. I liked it at first. After some time I got annoyed with iGo telling me to go the longer way, having wrong speed limits, and not finding some addresses. All that because of outdated maps. I tried to get updated maps for my country from the seller, without success, then from anywhere, without success. The same thing happened with Sygic on another unit. Only with these outdated maps I realised how quickly things can change and how important it is to have up-to-date maps.

So, TomTom is best for me, iGo for you, and everyone else will have their own best.

Yes, it's hardware. Chinese can be confusing. 800x480 and 1024x600 are both nominal and maximum resolutions supported by these displays. So, if you buy a unit with 800x480 display, you can't upgrade it to a higher resolution, you need to replace it (the display), and then flash it with a suitable rom.

It's the same screen size, and practically everything else is the same except resolution; that's why it's only $20 difference.
