I currently use navicomputer (Downloaded Offline Maps) on windows mobile phone and it is very useful when I got overseas as I can add in POI and just follow the route to the place.
However, as I am using Touch2, the screen size is a bit small so looking for alternative device with bigger screen.
I found OruxMaps for Android but have no chance to try it out as I have no Android device now.
Sad to hear this, doesn't really like carry another gadget. =/
Do you have any idea which MIC tablets have built-in-gps? How much did you pay for your bluetooth gps? Is it able to get a fix fast on cold startup?
I have tried OruxMaps for Android but i believe it doesn't have turn-by-turn navigation - it's more for trekking and geocaching. In that case, I would highly recommend Locus Pro/Locus Free. There's just no contest - it's the best trekking app for Android - just check out the rave reviews by users. If you know how, you can actually create offline Google maps on your PC and then load them onto Locus (previously you could even download Google maps directly within the app but Google stopped this). You can try out the free version which has most everthing but i bought the paid ver just to show support for the developer.
As for your second Q, i remember some earlier models like the HeroTab had built-in gps but it's outdated now. For the new ones, i am not aware of any.
Personally, I would advise you to get a bluetooth gps instead of relying on the MIC built-in gps which will likely be of poor quality. That way, it will be easier to find a MIC tablet with just bluetooth (or one which can support a bluetooth usb dongle) even if it doesnt have gps.
I bought my Holux bluetooth from DealExtreme - liked it so much that i bought another one as spare shortly after. There are 2 versions - 1 with memory (so you can download onto the pc and retrace the route on say, Google Earth) and 1 without memory. Think it cost ard S$60-S$70 each. There are probably cheaper models but I chose one that uses a removable standard Nokia BL-5C comaptible battery.
The advantages of using BT gps:-
- MUCH more sensitive, can get lock within 30s or so
- works with most (but not all) bluetooth devices. For iPad, need to jailbreak; for Android need to download free bluetooth gps app
- uses its own battery so will not consume your tablet/HP battery
- you can place the BT receiver independently from the device for best reception - for eg on the dashboard while someone holds the device
- it is extremely small and pocketable - ard matchbox size
I would suggest that you buy the BT gps first then bring it along to test with any tablet you plan to buy to make sure it connects. My HTC Legend refuses to connect but my Samsung Galaxy SL, Galaxy Tab and iPods/iPad/iPhone all connect effortlessly
