   It's easy to get another disc.   The car is a 2005 and when I bought it   
   in 2017 it had the original disc.  I don't really care about recently   
   built roads and streets -- there aren't that many of them -- but I also   
   realized the excess supply of discs would run out, so I bought a 2008   
   version about 3 years ago.  (2008 is the latest year Solaras were made.   
   Although a 2009 disc for other Toyotas might work fine, I didn't want   
   the risk.  By 2010 or a little later, they were no longer making new   
   DVDs because, as someone said, they use the Net, not DVDs, to supply   
   data.)   
      
   Until 2 or 3 years ago I could still find anything I owned but now I   
   can't guess where the 2005 DVD is.  I paid about $15 for the 2008 and   
   now it's $25 for another new one. on ebay. New, never used.   
      
      
   But the cleaning disc came yesterday after I asked about its risks and   
   before anyone answered telling me there really are risks, and I used it.   
   It appears to have worked.  The instructions say it can take 20 - 30   
   minutes, but I was right, because it's a Map DVD, it can't actually run,   
   and it spins only a couple minutes before it gives up.  3 or 4 minutes   
   later, it tries again, I'm pretty sure, every 3 or 4 minutes.   But I   
   only put in about 20 minutes of my time, which would be 7 minutes or   
   less of cleaning time, not 20 or 30 like they said.   
      
   It seemed to get better in stages and I've only started the radio 3   
   times since it worked completely, and today I sent away for an entire   
   unit, off-brand, for $69, just in case I go on this trip and it fails   
   while I'm away from home.
