RE: Transcend
I can confirm that his Transcend 1gb single layer does lock when receiving calls on his 2020i in TomTom 5.1, he also has a Bluetooth GPS Unit.
I have tried all the tricks on various forums, no joy, as I said, pop SD or turn GPS Off/On seems the only solution.
I have also noticed , that if I am running GPSinfo connected to BT338 to set Waas/Egnos. If I try and watch a video (Stored on my SD card) it keeps flicking out of full screen mode (WMedia player 10) and then freezes.
Which is not a problem as I only run GPSinfo for a few seconds, but it does seem to point to an issue between the Alpine SD hardware and the bluetooth hardware, maybe there is a shared componant at fault, which may point to a power issue?
The bad news is if it is an Alpine hardware problem, then there will be no software fix. That is probably why the sellers are fudging the issue, the Alpine has been out long enough for them to have found a software solution, of course they are not going to admit a hardware design flaw!
