Purchased the TireSafeGuard/Tyron system for new Phaeton 42' last August and it's never read all 12 pressures consistently. Lots of doubletalk from installing dealer re "it works, it's broke, it needs to go back etc"....after 6k miles, the dealer decided it was broke and sent the monitor back to Tyron (leaving the system void for 30 days)..reinstalled and said it's fixed (not)...then decided the system was supposed to have a signal booster installed (claims Tyon states any coach over 38 needs the booster)....
Tyron refuses to answer emails requesting return and refund, period. Dealer, at this point, sends out the booster saying have the booster installed and we'll pay the labor. Local RV tech sez he will not install and take on the liability. Thus far, 8000 miles and still a non-working system !!
