I have a system on my TT. It provides continuous air pressure and tire temp on a small screen suction cupped to the dash. I don't remember the brand name and the TT is in storage. The only thing I'd do differently is buy the type that allows air to be added "thru" the individual monitors on each wheel. I have to unscrew each monitor to add air, then replace it after airing up the tire, which is sometimes a bit inconvenient. For less than $400, I get a lot of peace of mind with my system so I'd definitely purchase them again.
