I have just bought the Audi one, £86 delivered from vagparts, if I sold the car would I take it out? Of course not, don't be silly, I'll sell with the car. If it goes wrong, I can go back to Audi. If my stereo goes wrong or I have a warranty claim, Audi can't use the Dension lead as an excuse not to repair or replace the stereo. Horses for courses I know, and we all recommend what we have just bought ourselves, but I say buy the Audi one. Oh and the Audi logo looks cool on start up rather than some shabby Dension logo. Oh and its cheaper too and comes with proper instructions. Oh and it will annoy everyone on here who has the Dension one, not because its better but because you've ignored their advice. Boo hoo. Plus I'd rather give the money to a firm who is supporting this club with discounts schemes etc.
