I briefly ran a simulated route from Hougang St 91 Blk 971A MSCP to Beach Road Golden Mile on my wife's iPhone 3GS to consider if I should buy iPhone 4. However, straight away from the start of the route, voice kept prompting left turns throughout a series of right turns even though the route is showing right turns correctly. Then when it finally made its way onto Yio Chu Kang road, I was expecting the route to turn right towards AMK Ave 3 CTE but instead, the route continues along YCK road towards Serangoon Interchange. It seems even though routing is set to fastest route, it is still taking the smaller roads instead of expressway like what my GMXT/GMPC would do. Then all of a sudden, the maps starts jumping around (can't remember where but I think when the route joins the end of Seragoon viaduct near the end of Aljunied Road Junction. The next thing I knew, the route is making it's way back to my starting point. I tried the same route a few times but each time, the maps will jump around along the route and then makes it way to my starting point instead of the end destination. I will try more routes to see if the same issue persist but in the meantime I would like to know if other is having the same issues or not. I've renamed the filenames as advised a few post back by the way.
Thanks.
Hi Carz,
My wife Iphone 4 is with M7.1 too, but no issue on the routing and voice. We didn't use it for long, just about 10min drive around Ipoh and we didn't find anything wrong with it.
On the part you mentioned the maps start jumping around, does it have to do with a GPS receiver is weak? I have seen this problem on GPS unit due to receiver is weak and only able to lock on 2 or 3 satelite instead of 4.
Just my 2-cents.

Brent.
