Aren't many of the handheld GPS devices, sold in WalMarts everywhere, made in China? Of course not every junk would need one, just one for every 10 or so, which would lead the others. Still, they'd be slaughtered when the got to Taiwan, unless some really serious disruption of Command and Control, as well as the ROC Air Force and Navy. Althought the PLA Air Force has many more planes than the ROC Air Force, most are older and less capable. However they have about as many, or slightly more, of the more modern aircraft as does the ROC. I suspect ROC pilots are much better trained though.
They would be unwise to rely on U.S. GPS sats, which they realize. I think that a land based system of signal towers would be a safer bet, and very inexpensive.

The Russian trainers and U.S. observers are universally unimpressed with PLAAF and PLANAF fighter pilots. Even though they have been getting better in recent years, they aren't ready for prime time. Dogfighting the ROC air force wouldn't go very well for them.
