For some reason, however, now when adding a vehicle from the alphabetical drop down list, the choices for the vehicle make terminates with Nissan (no entry available for Porsche, Volkswagen, Volvo, etc). ### 5/5 — 支持探险家P-7 Pro *2022-07-27* 可以用来连接P-7 Pro实时查看各类定位数据，还是很方便的。 ### 1/5 — 绝对差评 *2020-11-25* 软件本身不能查看gps卫星信息，还内购，还有购置它家产品才能显示卫星信息😭，受骗了，又不能退钱 ### 2/5 — Sehr viele Informationen, aber... *2020-09-24* das Display ist nicht drehbar. Somit von mir nur 2 Sterne da es essenziell ist. Bei einem xxl Telefon. ### 3/5 — letztes update... *2019-10-26* update 25.10.19 die app stürzt sofort ab. somit unbrauchbar. bitte um korrektur. ### 5/5 — GPS Buddy *2019-05-17* Viele Funktionen mit viel Sachverstand und Liebe konzipiert! ### 5/5 — very need snr *2018-07-21* very need snr signal sattelites, please make this in new version. better implement advertising than a paid program ### 5/5 — Great GPS App! *2018-01-16* Works well and is simple to use, highly recommended and free! ### 5/5 — Arigatou gozaimasu *2016-10-15* Arigatou gozaimasu ### 4/5 — Great Customer Service...Good App *2016-05-16* I really like the interface and have Harry's Laptimer Grand Prix Edition. I purchased both the In-App Add-Ons (GPS and Engine). I have a Vbox Sport, a GoPoint BT1 and a 2013 Audi S4 with APR tune. I've had a handful of questions getting the app configured and Harry has been crazy fast in responding...almost real time. I have only one real issue in that for my setup the HP and torque are not fully functional. Harry is helping me work through the issue, but other than this one minor issue, everything else works great and for the folks like me out there that like tons of data, this app is great. Thanks for making the app and please continue to make it better. If I can get the HP and torque working, it'll be a solid 5 star review from me. ## Frequently asked questions about Harry's GPS/OBD Buddy ### What is Harry's GPS/OBD Buddy?
