Just got word from Whereis - they say V15 will be out early 2009 but don't know the specific date... Anyway, seems from the price the quote for some v15 that the price wil be around $250 which is cheaper than the previous versions.
Can anyone confim which version is required for the E53 - Is it the VDO Dayton Carin version. Whereis could not advise me, helpful chaps.
