So as I work through a very frustrating communication (possible) error in my 2010 RR HSE I find my "Launch" brand ODB even with the "professional" version of software for the Land Rovers is near useless in trying to diagnose my possible module errors.

I see most people saying the IIDT is a must have, however after reviewing the RSW All comm is half to less the price.

As such can anyone point me in the direction of a comparison of capabilities and quality?

Thank you all.

Sam's Motor and Machine YouTube channel has covered a few alternatives. Not sure if it covers the specific one you are after but might be worth a watch nonetheless.

I would always recommend the IID tool, as their support is first class. I can’t speak for the others but the folks at Gap, especially Patrick is world class. Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

+1 for the IID tool and their commitment to supporting their product. Tom

+2 on the GAP for the mentioned reasons but also if you leave JLR ownership you can sell it on for hardly any loss. 2012 TDV8 Vogue (L322)

+3 GAP IID and great support from Patrick ( in Canada )

Its really nice to have something so small and that reliably works with my iPhone, I use it once a month to keep on top of things
