once i can work out the bugs with my iphone 5 and my x8500bhs i next want to do the add on gps.

has anyone used this or a similar add on from pioneer?

i would love to hear any feedback

I wouldn't wast my time. The navi software that Pioneer uses is garbage and there have also been several problems trying to get a bypass to work to unlock the navi features while moving. Apparently at least in the past the bypass that works for video didn't work well for navi. Once you actually get App radio to work   you will have about 4 or 5 compatible navi apps to choose from all of which are superior to the Pioneer options. You could go with iGo Primo and all of its in app purchases, have a far superior navi experience and save a lot of money.

ah yes i was reading that about the u220 and bypass's not working with it,  i will probably just stick to the appmode once i can get it working
