I'm sure I'm not the only person who likes to use the N95 as their in car sat nav at the same time as using it for MP3 playback. Hooked up with an FM transmitter it works nicely and you get your directions through the speakers cutting in over the music as required.
Up until a few weeks ago I was still on branded vodafone firmware and with nokia maps. I'd been avoiding debranding because I didn't want to lose the tracking feature but I got sick of the memory problems and the phone really struggled to even run Music player and Maps together without 1 just crashing out.
So I debranded and upgraded and wow what difference to the memory, and the speed of a gps lock fell from minutes to seconds. All good news you would think, but there seems to be one nasty side affect. Running sat nav by itself works just fine, nokia maps and route 66 do a good job, but if I try and run Music Player at the same time as either one it has a very nasty effect on the sat nav. It almost instantly starts to struggle to even hold a gps lock, and when it does, the directions and position on the map are all about 10-20 seconds behind where I actually am.
I've tested it enough to be sure it's the cause. It might not be the music player specifically and could just be contention with memory for any application I guess. With the old firmware it could run both without this particular issue, I just didn't dare touch anything knowing one would crash if so much as a text message arrived !
So has anyone else experienced the same problem, any theories on why, or possible solutions ?
